  • Front End Alignment

    don’t skip this

    I’ve seen a lot of buggy builds come through and the front-end alignment is almost always the last thing people think about, or they skip it entirely. Then they wonder why their car darts all over the place, wanders at speed, or gets a shimmy going that scares the daylights out of them. Most of the time it comes right back to alignment. Let’s go through it.

    Caster is the inclination of your kingpin or ball joints relative to each other. Top leaned back behind the bottom is positive caster, and that’s always what you want. It’s what makes your steering return to center after a turn and keeps things tracking straight down the road. Stock VW runs 3 to 3.5 degrees, which is perfectly fine for a standard Beetle at normal speeds. But you’re building a buggy, shortened wheelbase, driving faster, and that stock setting isn’t going to cut it. You want 5 to 6 degrees positive caster. Most quality buggy frames like Berrien already have 5 degrees built in, so you may be good to go right out of the gate.

    To check it, make sure the car is on a level surface with all four tires on the ground and properly inflated. This matters more than people think. You need a straight edge about 12 inches long and a digital protractor or inclinometer. Place the straight edge vertically between the upper and lower tubes on the beam, zero your protractor, set it on the straight edge and read your degrees. Simple as that.

    If you’re working with a shortened stock pan you’re probably sitting at 3 to 3.5 degrees and need to add some. Jack the front up under the frame head, not the beam, and loosen but don’t remove the four bolts holding the beam to the frame head. Slide your caster shims in between the lower tube and the frame head, snug everything back down and re-check. You’re shooting for at least 5 degrees, no more than 6. One more thing: it doesn’t matter if your frame is level, nose up or nose down. Caster is the relationship between the kingpins or ball joints and the road surface, not the frame.

    Camber is how vertical your wheel sits when pointed straight ahead. Factory spec is zero degrees, perfectly straight up and down. A slight negative camber, around minus half a degree with the top of the wheel leaning inward, is acceptable and actually works well with wider modern tires. To measure it, place your straight edge vertically against the rim, the rim itself and not the tire sidewall, and put your protractor on that. Whatever it reads, that’s your camber.

    How you adjust it depends on what front suspension you’re running. Ball joint front ends use an eccentric adjuster at the top ball joint. Look between the upper suspension arm and the spindle and you’ll see a large hex nut. Turning that moves the top of the wheel in or out until you hit your target. It’s pretty straightforward. Link pin and kingpin fronts are a different story. Camber is adjusted by moving shims on the link pins from one side to the other on the carrier, which means pulling the wheel and some brake components. It’s not terribly difficult but there are enough steps that you’ll want a VW service manual in hand before you dig in.

    Toe is the relationship between the front and rear measurements across your tires. Stock spec is 1/8 inch toe in, meaning the fronts of your tires are 1/8 inch closer together than the rears, slightly pigeon-toed. On hard surfaces this keeps your tires tracking straight and true. Toe out does the opposite and will have your buggy wandering all over the road. You might hear guys running the desert or dirt ovals say they run toe out, and they’re probably telling the truth, but that’s for loose surfaces and has no business on your street buggy.

    To measure, car sitting on the ground with all four corners down. Mark the center of the tread on each tire so you come back to the exact same spot every time. Take your measurements at the 9 o’clock position on the front of the tire and the 3 o’clock position on the rear, and use the same tape measure for everything. The total difference between the two measurements is your actual toe. For example, 50 1/16 inches at the rear and 49 15/16 at the front gives you exactly 1/8 inch toe in. If you prefer to use toe plates bolted to the wheel studs with tires removed, just make sure the suspension is loaded and that your measurement points are the same distance from the spindle center as the outside edge of your tire would be.

    None of this is overly complicated. It takes a little time and patience to do it right, but at the end of the day you’ll have a buggy that actually drives the way it’s supposed to, and that makes all the difference.

  • Buggy Brake Work

    getting the basics right…

    I’ve been around old Volkswagens and dune buggies long enough to tell you, once everything’s bolted up is when most folks get themselves into trouble.  I always take a minute and look things over.

    You’ve got the calipers mounted and centered on the discs, lines run, and a new master cylinder and reservoir in place, that’s all fine. But none of it means much if the basics aren’t right – now its time to bleed the brakes.

    First thing I check is the brake pedal free play. There needs to be about an eighth to a quarter inch between the push rod and the master cylinder plunger. I don’t guess at it, I make sure. If that plunger can’t come all the way back, the master cylinder won’t refill properly from the reservoir. I’ve seen perfectly good brake systems act faulty just because that adjustment was off.

    Then I look at the calipers. The pads should already be sitting against the discs on both sides, and the pistons should be up against the pads. If they’re not, you’re wasting time trying to bleed air out of a system that isn’t even positioned correctly yet. If I need to move the pistons in, I’ll usually disconnect the hose at the caliper and use a little shop air to bring them in. Quick and effective.

    Once I know everything is where it should be, I fill the reservoir — but only with fresh brake fluid from a sealed container. Brake fluid doesn’t tolerate being left open. It pulls moisture out of the air, and moisture is what ruins brake systems from the inside out. I don’t take chances there.

    Before I get into any pressure bleeding, I like to let gravity do some of the work. If the setup allows it, I’ll open all four bleeders and let fluid start working its way through the system on its own. Catch cans under each wheel, of course. Once I see fluid at each corner, I close them up. That step alone saves time and makes the rest of the job smoother.

    From there, I bleed the system. I’ve used every method over the years —manual two-person bleeding, vacuum pumps, pressure systems, even reverse bleeding setups. They all work if they’re used properly. The method matters less than the consistency.

    What does matter is the order. I always start with the wheel furthest from the master cylinder—right rear, then left rear, right front, and finally left front. That’s not a suggestion, that’s just how it’s done if you want all the air out.

    If I’m doing it manually, I make sure the pedal is worked slowly and allowed to return fully every time. When pressure builds, I open the bleeder, let the pedal drop, then close it before the pedal comes back up. No shortcuts. Rushing that step just puts air right back into the system.

    When I get a firm pedal, I don’t assume I’m done. I top off the reservoir, then take the car out and use the brakes enough to seat the pads. After that, it comes back into the shop for another look. I check fluid level again, and I look carefully for any signs of seepage. Even a small leak will show itself at this stage.

    Most of the time, I’ll do a quick final bleed at each wheel just to confirm there’s no air left — just clean fluid.

    Bleeding brakes isn’t complicated, but it does require patience and attention to detail. I’ve always treated it as one of those jobs where you either do it right the first time, or you end up doing it twice. When it’s done properly, you’ll feel it immediately — a solid pedal, consistent response, and a car that stops exactly when it should. That’s the standard I’ve always worked to.


    Alright now, the brakes are bled, the pedal feels good and firm, and you’ve checked over everything with no leaks showing up. You’re close—but don’t hang the tools up just yet. There’s one more step, and it’s an important one: bedding the brakes.

    Old timers like me call it “burnishing.” Same thing. What you’re doing is using a little heat and rotor rotation to transfer a thin layer of brake pad material onto the rotor surface. That helps the pads and rotors get acquainted proper-like. It improves braking performance, helps the pads last longer, and keeps those embarrassing squeals and screeches to a minimum.

    It’s simple enough, but it takes a little patience.

    The best method is what we call the 30/30/30 method:

    • 30 slow-downs
    • From 30 mph down to about 10 mph
    • With about 30 seconds of easy driving between each one so the pads can cool

    Notice I said slow-downs, not full stops. Don’t come to a complete stop. You want that rotor still turning so the pad material lays down nice and even. Sitting still with hot pads pressed against the rotor can leave uneven spots, and that’ll cause chatter later.

    There’s also the quicker method, the 10/65/30 method:

    • 10 slow-downs
    • From 65 mph down to 10 mph
    • With 30 seconds of cool-down driving between each one

    It works fine and gets the job done faster, but finding a safe place to do that can be a challenge. Around here, slowing from 65 to 10 on the wrong road might get you introduced to the front bumper of a dump truck—and trust me, that’s not part of the brake procedure.

    A lot of folks skip this step because the brakes feel “good enough” after a quick driveway test. Don’t be that guy.

    Take the extra time. Bed them in right.

    That way, you won’t be the fellow at the cruise-in with the nice buggy and the screechy brakes everyone hears before they see you.

  • Wiring Importance – Part 2

    the one that got away 🙂

    I ended Part 1 by saying that, in many cases, a complete rewiring simply makes more sense—and if you’re paying a shop to sort out a compromised system, it can often be the less expensive route in the long run. With today’s aftermarket harnesses, the process is far more straightforward than it used to be. With some planning and a methodical approach, there’s no reason you can’t produce a clean, reliable result.

    Before starting, make sure you have the right tools and materials on hand: wire cutting pliers, a proper wire stripping tool, quality crimping pliers, a heat gun or butane torch, heat-shrink butt connectors, heat-shrink tubing, eyelet terminals, a supply of 10-gauge black wire, dielectric grease, wire ties, and basic hardware like 1/4-inch bolts, lock nuts, and flat washers. Having the correct tools is not optional—poor connections are the root of most electrical failures.

    For harnesses, I’ve worked with several over the years, and I consistently come back to Rebel Wire. Their VW Bug and VW Bug Deluxe kits are both well thought out and user-friendly, particularly for buggy and kit car applications.

    When it comes to mounting the fuse block, I prefer placing it high on the passenger-side firewall. The exact location is flexible, but accessibility matters. At some point, you—or someone else—will need to service it, and convenience counts.

    Now, the most critical aspect of the entire job—and the area where I see the most consistent mistakes—is grounding.

    A fiberglass-bodied vehicle does not provide a natural ground path. Every electrical component—lights, gauges, accessories—must have its own dedicated ground path to the steel frame. The battery must be grounded to the frame, and the engine must also be grounded to the frame. These are not optional steps.

    Grounds should never be daisy-chained from one component to another. Each ground should be intentional and direct. Wherever you attach a ground to the frame, remove any paint or powder coating down to bare metal to ensure proper contact. Once secured, protect the connection with dielectric grease to prevent corrosion.

    If necessary, use buss bars or dedicated ground studs to keep things organized—but do not take shortcuts. A poor ground will create problems that are difficult to trace and even harder to diagnose.

    As you begin wiring, work one circuit at a time. I keep a 12-volt battery nearby along with a pair of jumper wires fitted with alligator clips. As each circuit is completed, I test it immediately. This confirms proper operation before moving on and prevents compounding mistakes. Always establish the ground connection first before applying power.

    Routing is equally important. Plan where the wires will run before securing them. Once everything is verified, bundle the wiring cleanly and protect it with split loom. A well-routed harness not only looks professional—it prevents future wear and failure.

    At the end of the day, wiring can either elevate a build or undermine it entirely. But if you approach it with patience and a structured process, there’s no reason it can’t be done correctly.

    And when it is done right, everything works the way it should—no surprises, no crossed circuits, and no situations where turning on the radio makes the left front turn signal blink.

  • Wiring Importance – Part 1

    the one that got away 🙂

    I’ve been around race cars and shop floors long enough to know that some mistakes never quite leave you.

    My first car – this would’ve been the early 1960s – I was about 14 years old, was a 1955 MG TF with a 327 Chevy engine fitted into it. It was raw, overpowered, and completely impractical… which is exactly why I loved it. To this day, it’s still the car I measure all others against.

    At some point I decided it deserved a proper paint job. So I started disassembling it—methodically at first—until I got to the fenders and the lighting. That’s where experience—or the lack of it—caught up with me.

    I cut the wires. No labels. No notes. No diagram. Just assumed I’d remember how it all went back together.

    But I didn’t remember…..

    What followed was frustration, second-guessing, and eventually walking away from the project altogether. I ended up trading that car for a 1956 Buick Roadmaster convertible, which was a fine automobile in its own right—but it wasn’t that MG. And even now, decades later, I still regret not finishing what I started.

    After years of building and maintaining sprint cars and specialty vehicles, I can tell you with confidence: wiring is one of the most common reasons good projects stall out. Not because it’s impossible – but because it demands patience, discipline, and attention to detail in a way that mechanical work often doesn’t.

    When I’m dealing with a car that’s already wired but poorly organized, I approach it the same way every time.

    First, I stop and assess. There’s always a tendency to start pulling things apart immediately—that’s a mistake. You need to understand what you’re looking at before you change anything. Even bad wiring has a pattern to it.

    Next, I look for obvious weaknesses. Loose connections, poor crimps, corrosion—these are often the root cause of larger issues. One compromised connection can create symptoms that look far more serious than they are.

    Grounding is critical, especially in fiberglass-bodied cars. Unlike steel-bodied vehicles, you don’t have a natural return path through the chassis. Every ground must be deliberate, clean, and secure. If it isn’t, you’ll spend hours chasing intermittent faults.

    From there, documentation becomes essential. Every wire that’s disconnected gets identified. Every wire that’s cut gets labeled on both ends. A simple method is to use masking tape flags with matching numbers—quick, effective, and reliable.

    I also make a basic diagram as I go. It doesn’t need to be formal—just clear enough that I can retrace my steps later without relying on memory.

    Because ultimately, electrical work comes down to time and patience. There’s no shortcut for either. And when you factor in labor, there are times—especially in a professional shop—where it’s more practical to remove a compromised wiring system entirely and install a new one.

    That approach isn’t about taking the easy way out. It’s about recognizing when starting over is the most efficient and reliable path forward.

    We’ll get into that in more detail in part two.

  • HARD RIDE – Lower your Tire Pressure 🙂

    a Hard Riding Buggy

    You know how the story goes. You finally button up that dune buggy you started way back when the world was spinning a little slower and gas was cheap. Every nut and bolt is just right – fresh bushings, new bearings, clean seals. Sharp wheels, brand-new rubber, and a set of shiny gas shocks that looked like they came straight off a race car.

    Then you take her out for that first cruise… and wham! Feels like you’re bouncing down a country road in a wooden buckboard wagon.

    Now don’t go blaming the build… the answer’s simple, and it’s right there in the numbers. That old Volkswagen Beetle you started with tipped the scales around 1,850 pounds. Your stripped-down buggy? Closer to 1,300. That’s a whole lot less weight pushing down on the suspension—nearly a third lighter, and that changes the whole ride.

    See, those gas shocks you bolted on? They’re fine for a full-bodied Beetle, but on a lightweight buggy they ride stiff as a brick. First trick I tell folks: swap ’em out for a good set of old-school oil-filled shocks. Nothing fancy—just honest hardware that lets the suspension breathe a little. Heck, some of the smoothest rides I’ve seen came from a decent set of used shocks with a little life left in ’em.

    You don’t need to be running sky-high pressure on a featherweight machine like this. For street cruising, try about 10 pounds up front and 15 in the rear if you’re rolling on 70 or 75 series tires. Got those lower-profile 60s? Run them at 18 to 22 at most, but keep ’em no lower than 18 all the way around – they’ve got shorter sidewalls and don’t flex the same way.

    Now between softer shocks and dialing in your tire pressure, you’ll feel a night-and-day difference. Smooth, easy, like a Sunday drive instead of a rodeo.

    Sure, if you really want to get fancy, you can start reworking torsion leaves or adding adjusters, but that’s getting into deep wrench territory. Most folks don’t need all that.

    Start simple. Let the car work with you, not against you. And before long, that buggy’s gonna ride the way it was meant to… cool, comfortable, and cruisin’ just right.

  • VW Exhaust Studs

    the oh crap moment…

    A couple weeks ago, we rolled out the revised ACME web page, fresh paint, clean lines, everything buttoned up just right. Looks sharp from the outside. But like any good build, the real work happened behind the scenes… long hours, busted knuckles, and a whole lot of patience.

    Which got me thinking about a job every old VW mechanic knows too well – exhaust studs. Or more accurately, broken exhaust studs.

    There’s nothing quite like staring down a snapped stud buried in a tired VW cylinder head. Around here, we’ve fought that battle more times than we care to count. What starts as a simple exhaust swap can turn into a slow, miserable dance with drill bits and extractors. If things go your way, maybe you save the threads with a HeliCoil. If not, well… that head just graduated to paperweight duty.

    Truth is, those studs never stood a chance. Steel stud, steel nut, years of heat cycles, road grime, and time – they don’t just stick, they become one. Then comes the moment: wrench in hand, a little pressure… then a little more… and just like that—snap. Now you’re holding half a stud and a whole lot of regret.

    So how do you stay out of that mess?

    Before you ever lean on that wrench, you warm things up. Get some heat into that nut, let the metal expand, break that stubborn bond. Then ease into it. Not brute force, just a steady hand.  If it starts to give, work it back and forth, nice and easy, like you’re reminding it who’s in charge. If it won’t budge, don’t fight it, add more heat and try again.

    You don’t need anything fancy either. A good old handheld torch from the local hardware store will do the trick just fine. Takes a little more time this way, but it beats the hell out of drilling, tapping, and praying you didn’t just ruin a perfectly good head.

    It’s an old lesson, one you only learn the hard way if you’re stubborn enough: patience saves parts.

    And when you finally spin those nuts off and bolt up that shiny new exhaust, do yourself a favor, reach for copper exhaust nuts. A little foresight now saves the next guy, or maybe future you, a whole lot of grief.

  • The Full Soft Top

    for today’s buggies…

    Back in the early days of dune buggies, the rule was simple: if you needed something for your buggy, someone in the hobby figured out how to make it. That same spirit still lives on at ACME.

    Over the years we’ve worked to keep the buggy tradition rolling by filling the gaps the industry leaves behind, just like we did by helping keep the Berrien name alive and continuing to build our custom tube chassis. The dune buggy world has always been about enthusiasts helping enthusiasts keep these fiberglass beauties on the road.

    Not long ago there was really only one source offering new “full soft tops” for dune buggies with side windows, etc.. Original tops could sometimes be found, but most had long since cracked, faded, or yellowed after decades in the sun.

    When that supplier decided to step away from the hobby a few years before COVID, we saw the same problem many buggy owners saw, great cars with not a good option for a full soft-top or a way to drive them when the weather turned.

    So ACME stepped in. We partnered with the same fabricator who had been producing the tops, keeping the same trusted design, fit, and quality buggy owners had relied on for years.

    Since 2019, ACME has proudly kept these tops available for today’s dune buggy community; new, simple, practical, and true to the classic buggy era. Because sometimes keeping the dune buggy era current, it isn’t just about bodies and chassis. Sometimes it’s about making sure the little things never disappear from the hobby.


    The Full Soft Top and kit comes with all Stainless Steel Hardware, SS snaps, SS mounting pins, a full storage bag, and a boot cover to store the soft top while folded down still on the buggy. ACME can also install onto your buggy at our regular hourly rates. Please contact us if you have any questions.

  • ACME Ships & Delivers

    Starting April 1st, there’s a new sound in the air… and it isn’t just the rumble of an air-cooled 1600 warming up in the driveway. It’s the promise of something better. ACME is bringing the parts you’ve been dreaming about, bodies, frames, and accessories, straight to your door, anywhere east of the Mississippi.

    Back in the day, getting your hands on fresh fiberglass meant crates, pallets, and freight companies that didn’t always understand what they were hauling. Between the cost of boxing everything up and the extra charges just to get it off the truck, a good portion of your budget disappeared before the build even began.

    We figured there had to be a better way. So we’re doing it the old-fashioned way – by loading up and delivering it ourselves.

    No more crating. No more pallet fees. No more lift gate charges just because your garage sits at the end of a quiet street instead of a loading dock. When ACME delivers, your body or chassis arrives the way it should—handled by people who know exactly what it is and why it matters.

    And just like any good road trip, we’re planning our routes with fellow enthusiasts in mind. By grouping multiple deliveries together, we can keep costs down and pass the savings along. The more stops we make, the better it gets for everyone along the way.

    Your delivery price will be based on distance and timing, and if we can line you up with other builders along the route, we’ll adjust your cost accordingly. Simple, fair, and built around the same spirit that started this whole movement.

    Why let ACME deliver your next project?

    • No crating or pallet fees
    • Lower cost than traditional freight
    • Delivery right to your home or shop
    • Less handling, less chance of damage
    • Flexible timing that works for real garages—not warehouses

    So if you’ve been holding off because getting your body or chassis home felt like half the battle, consider this your green light.

    Give us a call or click HERE to contact us.. Let’s get your project rolling—just like it would’ve been back when the dune buggy craze first kicked up dust. 🚗💨

  • Buggy Field Repair… experience & creativity.

    doing more with less 🙂

    A few years back at a Manx Club gathering up in New York, we had one of those moments that every buggy guy knows is coming sooner or later. Two buggies got a little too friendly with each other out on the road. Nothing major—just enough of a bump to bend some parts and put one of them out of commission.

    Back at the host hotel parking lot, the usual scene unfolded. Hoods were up, toolboxes came out, and before long half a dozen folks were leaning over the buggy figuring out what needed fixing. That’s the thing about the buggy crowd—everybody jumps in. Piece by piece we got things sorted out until just one problem remained. The tie rod was bent. Not just a little tweak either—it was pretty well pretzeled.

    Someone looked around and said what everybody was thinking:
    “Well… that’s it. We’re done. Nobody’s got a spare tie rod.”

    Now when you’ve spent enough years turning wrenches and racing on a tight budget, you learn there’s usually another way. So I spoke up. “No we’re not done, we’ll straighten it.” and that got a few puzzled looks.

    “How?” someone asked… “Well, the first thing you need is a couple blocks of wood.” and I never go anywhere without at least two blocks of wood. They’re one of the most useful tools you can carry, even if they don’t look like tools.

    We slid the blocks under the jack that lifts the trailer tongue, laid the bent tie rod across the blocks, and started cranking the jack down.
    Just like that—instant press. We worked it a little at a time. Crank down, check it, move it, crank again. After a couple tries the bend came right out of it. By the time we were done the tie rod was straight enough to run, the steering was back in line, and that buggy was back on the road.

    Truth is, that kind of thinking comes from racing. When I was racing, money was always tight. Spare parts weren’t something you could just throw in the trailer. If something broke, you fixed it—whatever it took. And when you’re at a track miles from home and you get tangled up early in the evening, you learn to improvise in a hurry. Especially if you need to qualify… so you can win just enough prize money to buy the gas to get home.

  • Electric Power Steering (EPS) – first ACME Buggy Prototype

    Power steering in our Buggies…

    The electric power steering (EPS) system installation has now been successfully completed on the first prototype Berrien Genesis Buggy. This initial installation served as a development and fitment exercise to verify component layout, steering geometry, and overall system integration within the chassis.

    At this stage, the remaining electrical work consists of routing the primary power feed directly to the battery. Because the EPS unit draws a relatively high current during operation—particularly at low vehicle speeds—it will be supplied by a dedicated power lead connected directly to the battery rather than routed through the standard fuse block. This ensures the steering system receives a stable voltage supply without overloading the vehicle’s accessory circuits. An appropriately rated inline fuse or circuit protection device will be incorporated into this feed to protect the system.

    The driver-adjustable gain control knob will also be installed in the dashboard once the final dash panel is fitted. This control allows the operator to vary the amount of steering assist provided by the EPS unit. In practical terms, the driver can dial in lighter steering effort for low-speed maneuvering—such as parking or navigating tight trails—or reduce assist at higher speeds to maintain proper steering feel and road feedback.

    From a mechanical standpoint, the prototype installation utilized a fixed intermediate steering shaft between the two universal joints. For the production version, this shaft will be upgraded to a 3/4-inch double-D intermediate shaft. The double-D design provides two important advantages. First, it allows for slight telescoping adjustment, accommodating variations in the distance between the firewall and the steering box that may occur due to manufacturing tolerances, body mounting differences, or chassis variations. Second, the double-D profile provides a positive mechanical engagement that prevents rotational slippage while still allowing for easier installation and alignment.

    With the EPS unit mounted, steering linkage aligned, and the intermediate shaft configuration finalized, the system now integrates cleanly into the steering column assembly while maintaining proper steering geometry and structural integrity. Once the final electrical connections and dashboard controls are installed, the vehicle will be ready for operational testing to evaluate steering feel, assist levels, and long-term reliability under real driving conditions.

    Please contact us for more information on this innovative approach.

  • ACME Flake Technique – how it shines…

    ACME Standards…

    If you’ve ever stood next to one of our buggy bodies in the sunlight and watched the color explode with sparkle, you might wonder how that effect actually gets into the fiberglass. It isn’t paint—and it isn’t a shortcut. The shine starts right in the mold, and it’s the result of a careful step-by-step laminating process that combines proper mold prep, metal flake technique, and good fiberglass practice.

    The first step is prepping the mold. Before anything is sprayed, the mold has to be perfectly clean and properly waxed. Any dust, residue, or missed wax can ruin a finish, so we take the time to clean the mold thoroughly and apply mold release wax so the body will separate cleanly once it’s cured.

    Next we prepare all the gel coats that will be used in the process. That includes a UV-resistant clear gel coat and a second batch of clear gel coat mixed with the cobalt blue metal flake. Getting the mix right ahead of time keeps the spraying process consistent and ensures the flake stays evenly suspended in the material.

    Once everything is ready, we spray an initial layer of clear gel coat into the mold. This first coat becomes the outer surface of the finished body, providing depth and a smooth protective layer over the flake.

    After that flashes off slightly, we spray a very thin, quick layer of clear gel coat mixed with metal flake. This light coat is an important trick of the trade. Because it’s applied lightly, the flakes tend to stand up more instead of laying completely flat, which helps them catch and reflect light. That’s what gives the body that extra sparkle when sunlight hits it.

    With that sparkle layer in place, we then spray a heavier coat of the clear gel coat and metal flake mixture, making sure the entire mold surface is evenly covered. This is where the body really gets its color density and consistent flake coverage. Once that layer is applied, we allow it to cure properly before moving on.

    After curing, we go back and apply what we call “puddy.” Puddy is simply a thicker version of the clear gel coat with metal flake mixed in. It’s used to fill tight areas of the mold—corners, sharp 90-degree sections, and deep crevices where sprayed material may not have fully built up. This ensures those areas stay strong and that the flake coverage remains consistent throughout the body.

    Once the surface layers are complete, we begin the structural fiberglass work by chopping fiberglass into the mold and rolling it out. The chopped glass is saturated with resin and worked carefully with rollers to remove air pockets and ensure the laminate bonds tightly to the gel coat layers. After this stage, the body is again allowed to cure.

    Next we begin laying fiberglass sheeting and mats, building up the structural thickness of the body. These layers add the strength that allows the body to handle vibration, mounting stress, and years of driving. Once the reinforcement layers are in place, they are also left to fully cure.

    After the fiberglass structure is complete, the inside of the body is backed with a black gel coat. This seals the fiberglass laminate, protects it from moisture, and gives the inside of the body a clean, finished appearance. Again, we allow this layer to cure thoroughly before removing the part from the mold.

    With everything fully cured, it’s finally time for one of the most satisfying moments in the shop: popping the body from the mold. When the mold releases, the glossy flake finish that was built inside the mold is revealed.

    From there we move into the finishing work. The mold flanges are ground off, the edges are cleaned up, and the body begins to look like the dune buggy everyone recognizes. Finally, the surface is buffed to bring out the deep shine, and the hood is fitted and mounted so the body is ready for the next stage of the build.

    It’s a process that takes time and attention to detail, but doing it this way means the sparkle, color, and finish are molded directly into the body itself. The result is that classic dune buggy look—deep color, brilliant flake, and a finish that will keep shining for years.

  • Fiberglass Technique – Strength where it matters…

    ACME Standards…

    When you’ve worked with fiberglass long enough, you learn that real strength doesn’t come from simply piling on more material. It comes from placing the right material in the right locations. That philosophy is a big part of how we build our dune buggy bodies.

    At this stage of the layup process, we install one of the most important reinforcement materials used in the body: woven fiberglass boat cloth. Unlike the chopped strand mat commonly used in many production bodies, woven cloth contains continuous fibers running in two directions. Those continuous fibers greatly increase panel strength and rigidity while keeping weight to a minimum. It’s the same type of material that has been used for decades in boat hull construction, where durability, flexibility, and structural integrity are critical.

    Each section of the body is reinforced with a specific type of fiberglass mat depending on the loads and stresses that area will experience. Woven fiberglass cloth is used in areas that benefit from high directional strength and rigidity, such as the body sides and bottom mounting flange, the rear tail light mounting area, and the front fenders. In areas that require good contour conformity and impact resistance—like the dash and hood corners—we use chopped strand mat, which conforms easily to tight curves and complex shapes. The center section of the hood uses a core mat, which increases stiffness across a larger flat area without adding unnecessary weight. By selecting the proper reinforcement material for each location, the body gains strength exactly where it is needed rather than simply becoming heavier.

    Another major advantage of woven cloth and properly layered laminates is how effectively they integrate into the overall structure of the body. When each layer is properly saturated with resin and rolled to remove trapped air, the fiberglass becomes part of a unified laminate structure. The fibers interlock between layers of cloth, mat, and resin, creating a panel that is both lightweight and highly resistant to cracking.

    The process itself is straightforward but requires careful attention to detail. Each piece of reinforcement material—whether woven cloth, chopped strand mat, or core mat—is first cut and dry-fitted so it follows the contours of the mold without bunching or wrinkles. Resin is then applied and worked thoroughly through the fibers using laminating rollers, as you can see in the video, and brushes until the material is completely saturated. Extra care is taken in tight corners, mounting flanges, and reinforced sections to ensure the fiberglass conforms tightly to the mold surface and underlying layers. Any trapped air is carefully rolled out so the laminate lays perfectly flat, allowing each layer to bond tightly with the next and become part of a single, solid structural panel rather than separate layers sitting on top of one another.

    Building bodies this way provides the best balance of strength and weight. The body remains light enough for proper suspension performance and vehicle balance, while the reinforced areas handle years of vibration, flex, and real-world driving without developing stress cracks.

    In short, we’re not just adding fiberglass—we’re engineering strength into the body. The careful placement of woven cloth, chopped mat, and structural core materials is one of the reasons these buggy bodies remain solid, durable, and dependable long after they leave the shop.

  • Why Buy an ACME / Berrien Buggy Frame ?

    the foundation…

    The foundation of any vehicle structure determines its strength, durability, and safety. From a structural engineering perspective, the chassis is the primary load-bearing component of a dune buggy. Every force generated by the suspension, drivetrain, terrain, and occupants ultimately travels through the frame. For that reason, the Berrien Buggy frame is engineered as a rigid, purpose-built structure rather than a modified production component.

    True Perimeter Frame Architecture

    The Berrien frame utilizes a true perimeter frame design, where the primary longitudinal frame rails are positioned along the outer edges of the vehicle body rather than concentrated near the centerline. This configuration significantly improves torsional rigidity and side-impact resistance, two critical parameters in lightweight recreational vehicles.

    The primary rails are constructed from 2″ × 2″ × 1/8″ wall domestic square steel tubing with a fusion-welded seam, selected to provide an optimal balance of stiffness, weight, and structural durability. Secondary longitudinal members consist of 1 1/2″ square tubing, while the front suspension mounting structure incorporates 1 1/2″ round tubing formed into front suspension hoops.

    This triangulated and distributed structure allows loads to be transferred efficiently through the frame while minimizing localized stress concentrations.

    Front Suspension Integration

    At the front of the chassis, the VW Type 1 front beam assembly is mounted using a clamped interface to the dual front hoops. This mounting method achieves two structural advantages:

    1. Wider load distribution – Unlike the original VW frame head, which concentrates loads at a central mounting point, the Berrien design spreads forces across a wider section of the chassis. This greatly reduces torsional deflection and eliminates leverage forces acting on a single structural node.
    2. Structural cross-member function – The beam is secured at four clamping points, allowing it to act as a structural cross-member within the frame assembly. This effectively increases lateral stiffness and contributes additional torsional strength to the overall chassis system.
    Rear Torsion Housing Integration

    At the rear of the frame, the re-tasked VW torsion housing assembly is welded to a full-width rear cross-member at four structural attachment points. Similar to the front mounting strategy, the wider interface distributes loads across a larger structural footprint.

    Once integrated, the rear torsion housing becomes an active structural component of the chassis rather than merely a suspension mounting point. This design further enhances torsional stiffness and improves load transfer through the rear suspension system.

    Why Torsional Rigidity Matters

    Torsional rigidity is a critical factor in the performance and durability of any vehicle frame. When a chassis flexes excessively, suspension geometry changes under load, steering precision decreases, and structural fatigue can occur over time.

    This consideration is especially important in dune buggies because fiberglass bodies do not provide significant structural reinforcement. Unlike the original steel Volkswagen Beetle body, which contributes to chassis stiffness, a fiberglass buggy body primarily functions as a lightweight shell. As a result, the frame must provide nearly all of the vehicle’s structural integrity.

    For this reason, a purpose-built chassis with high torsional rigidity is essential for predictable handling, durability, and long-term safety.

    Key Advantages of the Berrien Frame
    • All-new structural steel, with the exception of the re-tasked VW torsion housing
    • Significantly increased torsional stiffness compared to shortened VW floor pans
    • Integrated fiberglass floor pan that will not rust or corrode
    • Service access to the tunnel from underneath the vehicle, simplifying maintenance
    • Built-in provisions for hydraulic clutch systems
    • Precision jig-welded construction to ensure dimensional accuracy, squareness, and level alignment
    • Designed for Volkswagen Type 1 components, allowing direct bolt-on installation
    • No welding or fabrication required by the builder
    A Purpose-Built Foundation

    Berrien frames provide a structurally engineered foundation for a dune buggy build. By eliminating the need to shorten and modify a vintage VW floor pan, builders save significant fabrication time while gaining a chassis that is stronger, more precise, and better suited for fiberglass buggy construction.

    The result is a vehicle that is not only easier to build—but also more rigid, safer, and far more enjoyable to drive.

  • Origins of ACME: the Nostalgia Chassis & why it mattered…

    the Nostalgia Chassis

    “When people ask me what mattered most when we were deciding whether to buy Berrien Buggy, my answer usually surprises them. It wasn’t a body style or a name—it was the Nostalgia chassis.

    At the time, Acme Car Company was still young. We had shortened a handful of Volkswagen pans for customers who wanted to build buggies, and while we did the work carefully, I never felt completely right about it. We were starting with old, often rusty steel that had already lived a hard life. Volkswagen never intended those pans to be cut apart and re-used the way we were using them.

    We had fixtures. We had a jig table. Everything went back together level and square, and the welds were solid. But even doing everything “right,” I couldn’t shake the feeling that we were asking too much of something that was never designed for it. My reservations stuck with me.

    Then came our first order as a Berrien dealer—and with it, a Nostalgia frame.

    When that chassis arrived and I really looked it over, the decision became obvious. The strength was there. The design made sense. The fiberglass floor pan was clean and purposeful, and the ability to access everything from underneath made building and maintaining the car easier and smarter. Right then, I knew Acme would never shorten another VW pan.

    That single frame changed the direction of the company. Honestly, without the Nostalgia chassis in Berrien’s lineup, I doubt you’d be reading this today. It mattered that much to me.

    I’ll choose strength over “tradition” every time. You can build things the way they used to be built—but I’ve walked away from too many crashed race cars not to respect what real strength means. Some lessons stay with you for life, and this was one of them.”

    A Founder’s Story

    “I never planned on building a company or leaving a legacy. I only wanted to build things and understand how they worked.

    I was born in Harrisburg, Pennsylvania, and from the beginning I was drawn to machines with wheels. A visit to Williams Grove Speedway when I was five years old set something in motion that never really stopped. From wooden soapbox racers to go-karts, and eventually full race cars, I learned early that the best lessons come from doing the work yourself. When I broke a go-kart frame at eleven, I wasn’t given a repair—I was shown how to weld. That moment stayed with me.

    Over the years, life took me through many roles: mechanic, welder, truck driver, airframe repairman, racer, builder, crew chief, and father. Racing sprint cars became my greatest teacher. With little money and a lot of responsibility, I learned to build what I needed, fix what broke, and keep improving. Racing has a way of telling you the truth. If something isn’t right, it won’t last.

    When my sprint car days ended in 2011, I slowed down—but I didn’t stop. Acme Car Company gave me a place to keep building, just at a different pace. Dune buggies allowed me to apply a lifetime of lessons with care and intention. Even now, I still find myself thinking about how something could be made a little better.

    At this stage of life, I understand that none of this was done alone. I was fortunate to cross paths with many generous teachers, friends, and competitors along the way. I was especially honored to have known Bruce Meyers. His vision created the culture we all enjoy today, and it has been a privilege to carry a small part of that forward.”
