Custom builders looking to equip their C1- or C2-generation Chevrolet Corvette with an independent rear suspension (IRS) can do so via Roadster Shop’s new SPEC7 chassis.
The features on the new chassis include C7-generation Chevrolet Corvette suspension geometry and OEM components, making serviceability that much more convenient. The chassis also comes with the right track width to accommodate the appropriate running gear.
“For years, builders have looked to the C6 / C7 platform for their early Vettes,” Roadster Shop explains in the product description. “Unfortunately, the wider track width requires the use of less than desirable flush, factory-style wheels. RS has solved that problem by engineering the SPEC7 chassis to retain C7 components and geometry while packaging them in an impressive 56-inch track width, allowing for period appropriate wheels with a more visually desirable offset.”
The rear frame rails can accommodate a 345 section-width tire when mini-tubbed, while a ZL1 9.9-inch rear differential with 3.73 gearing and limited-slip posi traction puts the power down. The IRS drive axles are rated up to 800 horsepower. Roadster Shop is also offering optional engine mounts for LS and LT V8 engines.
Final details include crossmember and chassis bracing clearance for a three-inch exhaust, power rack and pinion steering components, billet coilover suspension, and accommodation for the factory body, bumper, and core support mounting locations.
This new custom chassis looks like it’s a perfect fit for those builders that want to combine the old-school styling of a C1- or C2-generation Chevrolet Corvette, with the modern suspension and underpinnings of the C7-generation Vette.
Pricing for the complete IRS chassis starts at $20,995, with optional extras like the LS / LT engine mounts, C7-generation brake upgrades, and sway bar packages adding to the bottom line.

Very nice product!
I know, I know, but if you’re doing that that perfect, why not finish it the rest of the way with a transaxle? Just sayin’…
It has been years since I read about new chassis for older vehicles. This may be the spark to reignite rebuilders to continue to work on the older Corvette generations, and offer new specifications for potential customers. This may be an aftermarket product but it is a great idea.
Transaxles are much more expensive and much harder to find than conventional transmissions and rear ends. You plan on bankrolling those transaxle purchases?
Now all we need is some aftermarket manufacturer to bring out a line of high-quality, GM approved, fiberglass body shells for the C1 to C7 generations, for these chassis, sold, maybe, through the various Corvette catalog parts stores, not unlike those Ford and Chevy catalogs that sell body shells for the early Mustangs and Camaros. Drop in a LS crate engine, and your choice of a Tremec 5 or 6 speed transmission, or an 8 or 10 speed automatic, some Brembo brakes and a Borla or Magnaflow, exhaust system, and you’d have a sweet ride. Many of the body pieces as well as virtually all the interior pieces are available through those catalogs It wouldn’t be cheap, but it certainly would be fun to do. Of course, by the time all is said and done, one could buy a new C8 Z06, when it is released, for about the same, or maybe even less cash!
