A pristine ‘Vette from the 1950s or 1960s doesn’t need a new and improved chassis because that would hurt the car’s value. However, a rustbucket could use the SPEC7 Series from Roadster Shop.
Don’t think that the aftermarket chassis comes cheap, though. At $20,995 right off the bat, you could say that Roadster Shop is asking too much money for this upgrade. The thing is, opting for the SPEC7 translates to aluminum control arms, spindles, and independent rear suspension from the C7.
Compatible with both the first- and second-generation Corvette, the chassis utilizes the factory body, bumpers, and core support mounts to make the swap as easy as possible. Standard features also include a limited-slip posi Camaro ZL1 9.9-inch diff with 3.73 gearing, a drive axle that can handle 800 HP (811 PS) as standard, and frame rails for rear tires as wide as 345s.
Mount options? Roadster Shop offers a few of those as well, starting with LS and LT engine mounts at $250 or $350, respectively. A transmission adapter for the 8L90 torque-converter automatic of the C7 Corvette is also available at $150, front and rear sway bars cost $495 per piece, stainless brake lines are $995, and the e-brake will set you back $395. Stopping power options come in the guise of Z51 brakes with black calipers and 13.5-inch vented and slotted rotors for the front and rear ends at $2,305 and $1,865, respectively.
The most important thing about swapping the original chassis of the C1 or C2 with the SPEC7 Series is that the OEM components make servicing a lot easier while the suspension geometry and track width improve the car’s handling. Rack-and-pinion power steering and coilovers are two other highlights.
But most importantly, Roadster Shop says that the SPEC7 has “nearly the same cost as our competitors’ solid-axle chassis.” Given the dynamic capabilities of the seventh-generation Corvette, the C1 or C2 with this hardware upgrade could easily be considering pro-touring cars.
A live axle, on the other hand, is the better choice for strip slaying.
