The Superformance Corvette Grand Sport is a remarkable tribute to Zora Arkus-Duntov’s 1963 lightweight racing cars. The first-ever example produced by Superformance, this sleek machine blends vintage racing heritage with modern performance and technology. Finished in a striking silver with red and gray stripes, this Grand Sport captures the essence of the original Corvette racing legend while offering thrilling driving experiences for modern enthusiasts.
Power and Performance
Under the hood, this Grand Sport packs a 377ci V8 engine built around a Dart block and aluminum cylinder heads. It’s topped with an Inglese eight-stack induction system fed by four Weber 45DCOE carburetors, giving it a potent performance boost. With an MSD distributor, Optima red-top battery, and an aluminum radiator, this engine is designed to impress. The power is harnessed through a Muncie M-22 four-speed manual transmission and a 3.73:1 Positraction differential, ensuring smooth and precise handling on any track or road. The long-tube headers are wrapped in heat insulation, feeding into the car’s side exhaust pipes, delivering both power and a signature racing sound.
Timeless Styling and Advanced Engineering
The Superformance Corvette Grand Sport’s hand-laminated fiberglass body sits on a four-inch steel tube chassis, perfectly replicating the look and feel of the 1963 Grand Sport models. The silver finish, combined with red and gray racing stripes and ivory roundels, makes for a visually stunning tribute. The car is equipped with a vented hood, front fenders, clear headlight covers, and rear fender flare extensions that all enhance the car’s aerodynamic profile. Bullet-style mirrors and a rear-axle cooler mounted to the rear deck complete the racing-inspired design.
Handling and Suspension
The car’s suspension is built for performance, featuring adjustable front coilovers and a rear three-link setup with a transverse leaf spring. The 15” Halibrand magnesium knock-off wheels are fitted with Avon tires, providing an ideal balance of grip and handling. The car’s power-assisted four-wheel disc brakes ensure stopping power in any driving condition. A power rack-and-pinion steering system makes for responsive and agile handling, whether on the track or open roads.
Classic Interior with Modern Comfort
Inside, the cabin mirrors the spartan style of the 1963 Grand Sport. Blue leather upholstery and carpeting complement the minimalist dash, providing a racing-inspired yet comfortable environment. Modern amenities like Vintage Air climate control, power windows, and three-point seat belts are added for convenience and safety, ensuring the car remains comfortable for extended drives.
