Last weekend at Goodguys Ft. Worth, Texas, RideTech proved that a 100% bolt-together, all-steel Camaro with a stock subframe can run with the pros. In other words, a pure street car competed against lightweight tube chassis hot rods in the Pro class — rather than the Street Machine class. The 48 Hour Camaro finished in sixth place. Stats can be seen HERE.
We realize that most of you will never race your car. That’s why RideTech goes out of its way to build and race true street cars. We develop components to help you make the most of your stock chassis. The 48 Hour Camaro retains its stock, original 1970 subframe — which has never been removed from the car. No welding occurred during the build — ZERO. Each and every part used on the 48 Hour Camaro (other than the custom upholstery) is commercially available. While you may never race your own car, it’s good to know that the performance potential has been tested in real world competition and readily available.
The secret to the 48 Hour Camaro’s performance is a balanced combination of parts and systems. The Lingenfelter Performance LS3 makes power across the entire rev range. Goodguys Autocross tracks feature tight, low-speed hairpins that require power from 2200 rpm right up to redline. The 550 HP LPE LS3 delivers. It’s mated to a close ratio Bowler Transmissions 4L75E 4 speed automatic with Sonnax internals. Like a manual transmission, the design provides engine braking when heading into corners. The billet Pro Torque converter feels tight at low throttle, but lets the engine scream at wide open throttle. Pro-Torque is really onto something. Their converter design keeps the engine and trans coupled despite quick and frequent changes in throttle angle. Power gets to the ground by way of a bolt-in Currie Turn 9 “Crate” rear axle that feature MillerBuilt floater housing ends.
While many pro-touring cars feature mini-tubs, subframe connectors and tubular subframes the 48 Hour Camaro’s relies entirely on a stock, unmodified unibody and subframe using 100% bolt on suspension including RideTech’s all new Bolt-In 4-Link with “unicradle” rear subframe. Holes have been drilled to accommodate the upper link pass-through openings, but zero welding occurred during this install. The new “unicradle” design locates the upper and lower link points exactly where they need to be for balanced handling and traction. As part of a complete suspension package that includes StrongArm front suspension and monotube coilovers, the 48 Hour Camaro feels settled and sure-footed during cornering and hard braking. Turn-in and feedback inspire confidence.
Between the powertrain and the chassis, there really is a supercar hiding in this 1970 Camaro. Best of all, you can duplicate this combination in your own garage without a welder or fancy tools. To help you achieve that goal, we documented every installed part into a shopping list that can be found HERE.
Our friends at Summit Racing Equipment have taken our build sheet to an entirely different level by compiling six “48 Hour Camaro Combos” that make it easy to order a variety of vehicle systems with the click of a button. You can find those combos HERE or by searching 48 Hour Camaro on SummitRacing.com.
The 48 Hour Camaro might never win a Goodguys Autocross Pro class competition as the field includes many flyweight, tube chassis hot rods. Like our Track 1 Camaro, Pro class cars have massive 315mm and or 335mm tires and big power. It’s nice to know, however, that the 48 Hour Camaro — with its smaller 275 wide tires — can run with the big doggies. …and we’re just getting started.
