2011 Chevrolet Corvette Convertible Grand Sport Callaway SC606 6-Speed C6

This 2011 Chevrolet Corvette Grand Sport convertible was sold new at Criswell Chevrolet of Gaithersburg, Maryland, and was modified by Callaway Cars of Old Lyme, Connecticut, with the company’s SC606 Package. The 6.2-liter LS3 V8 was fitted with a TVS2300 supercharger, an intercooler, high-flow fuel injectors, a Honker intake system, and a Callaway Double-D exhaust system. Exhaust slats and a short-throw shifter were also optioned and the car is finished in Crystal Red Metallic Tintcoat over Titanium Gray leather upholstery. Additional features include a six-speed manual transaxle, a limited-slip differential, xenon headlights, five-spoke alloy wheels, power-adjustable seats, a head-up display, dual-zone automatic climate control, and a Kenwood touchscreen infotainment system. The current owner acquired the car in 2017 and subsequent work consisted of servicing the brakes and installing four tires. This SC606 is offered with a Callaway build sheet and Certificate of Authenticity as well as a spare radio and a clean Pennsylvania title in the seller’s name. The Grand Sport features wider fenders along with additional brake cooling ducts ahead of the rear wheels. This example is finished in Crystal Red Metallic Tintcoat and features a power-retractable black soft top, an exposed carbon-fiber hood bulge, xenon headlights, fog lights, hash mark fender stripes, Callaway and Grand Sport badging, and a stainless-steel Callaway “Double-D” exhaust system with optional exhaust slats.   Staggered-diameter 18″ and 19″ five-spoke alloy wheels are mounted with Michelin Pilot Sport 4S tires measuring 275/35 up front and 325/30 out back. The tires are said to have been installed in 2024. Braking is handled by six-piston front and four-piston rear calipers over ventilated rotors sized 14″ and 13.4″, respectively. The Grand Sport features specific stabilizer bars and stiffer springs and shock absorbers when compared with the standard Corvette. The cabin features heated power-adjustable bucket seats upholstered in Ebony leather with Titanium Gray inserts. Interior amenities include a head-up display, a Kenwood touchscreen infotainment system, a backup camera, side airbags, Keyless Access, cruise control, and dual-zone automatic climate control. A Callaway plaque is mounted to the center console and displays the vehicle’s VIN. Additional Callaway elements consist of a short-throw shifter, embroidered floor mats, and branded door sill plates. The leather-wrapped three-spoke steering wheel frames a 200-mph speedometer and a tachometer with a 6,500-rpm redline as well as gauges for coolant temperature, oil pressure, voltage, and fuel level. The digital odometer indicates 35k miles, approximately 25k of which were added under current ownership. The 6.2-liter LS3 V8 was modified by Callaway with a TVS2300 roots-style supercharger, a Honker high-flow intake system, an air-to-liquid intercooler integrated into the intake manifold, a high-flow fuel pump and injectors, and an auxiliary fuel pump controller. The carbon-fiber injector covers feature Callaway logos, and Callaway rated the engine at 606 horsepower and 553 lb-ft of torque. Power is sent to the rear wheels through a six-speed manual transaxle and a 3.42:1 limited-slip differential. A Callaway build sheet and Certificate of Authenticity accompany the vehicle along with two remote keys and the removed radio. The Carfax report shows no accidents or other damage.
