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.
