Listed for sale on PCARMARKET, this Superformance Corvette Grand Sport represents a modern, GM-authorized continuation interpretation of Zora Arkus-Duntov’s iconic 1963 Grand Sport racing program. Built as a faithful tribute to Chevrolet’s most legendary lightweight endurance racer, the car recreates the aggressive aesthetics and competition-focused spirit of the original factory prototypes while incorporating contemporary engineering and reliability.
Finished in blue with a white center stripe outlined in red, the exterior features traditional #2 racing roundels on the hood, doors, and rear deck. Staggered American Racing Shelby Cobra-style wheels measure 17 inches at the front and 18 inches at the rear, wrapped in Nitto NT555 performance tires.
The hand-laminated fiberglass body is mounted to a 4-inch tubular steel chassis and incorporates period-correct Grand Sport design elements, including a vented hood, flared fenders, headlamp covers, bullet-style mirrors, and an externally mounted rear differential cooler.
Power comes from a supercharged 6.2-liter LS9 V8 engine sourced from the C6 Corvette ZR1 and factory-rated at 638 horsepower, with this application producing approximately 635 horsepower. The engine features dry-sump lubrication and a custom EVAP breather system, delivering modern supercar performance in a vintage racing package. A Tremec T56 six-speed manual transmission sends power to the rear wheels, supported by ceramic-coated headers and a custom stainless-steel side-exit exhaust system.
The chassis is equipped with tubular control arms, adjustable front coilovers, and a rear C2 Corvette-style three-link suspension with a transverse leaf spring and Bilstein dampers, balancing period-correct geometry with modern adjustability. Braking performance is handled by power-assisted Wilwood four-wheel disc brakes.
Inside, the cabin is trimmed in black leather with matching door panels and carpeting, blending race-inspired minimalism with street usability. Features include bucket seats, Vintage Air climate control, power windows and locks, Dynamat sound insulation in the rear compartment, a custom center switch panel, an analog clock, a GT-style steering wheel on a tilt column, and a cockpit-mounted fire extinguisher.
This Superformance Grand Sport ultimately delivers a contemporary interpretation of a historic racing icon, combining authentic styling cues with modern LS-based performance and usability.
