The 6.2-liter LS3 V8 was fitted with a supercharger, intercooler, and larger fuel injectors, and an upgraded exhaust system, carbon-fiber front splitter, and “PowerBulge” hood were also installed. The car is finished in Cyber Gray Metallic over a gray interior and equipped with a six-speed manual transaxle, a limited-slip differential, translucent removable roof panel, carbon-fiber rear wing, Pioneer touchscreen stereo, aftermarket rear-view camera, 18″ and 19″ Cray Astoria wheels, and the 3LT interior package, which includes Bose audio, a head-up display, heated and power-adjustable seats, and a power telescoping steering wheel.
The car is finished in Cyber Gray Metallic and features white fender stripes outlined in gray as part of the Grand Sport Heritage Package. Additional exterior features include a translucent removable roof panel, front and rear fender vents, Callaway and Grand Sport badging, and a rear-view camera. The “Double-D” exhaust system features optional exhaust slats, and carbon-fiber components include a front splitter, rear wing, and “PowerBulge” hood.
Staggered-diameter Cray Astoria wheels are finished in black and mounted with 285/35 front and 345/35 rear Michelin Pilot Super Sport tires showing 2020 date codes. The Grand Sport featured stiffer springs and larger stabilizer bars than the standard Corvette. Stopping power is provided by multi-piston Corvette-branded brake calipers and cross-drilled rotors all around.
The cockpit features heated power-adjustable bucket seats upholstered in black leather with perforated Titanium Gray inserts and Grand Sport embroidery in the headrests. Amenities include a power telescoping steering wheel, head-up display, Bose audio, the Memory Package, dual-zone automatic climate control, a Pioneer touchscreen stereo, and a Callaway short-throw shifter. The fuel door lock actuator sticks occasionally and needs to be reset by hand.
A Callaway plaque is mounted to the center console and displays the VIN.
The leather-wrapped steering wheel frames a 200-mph speedometer, a 7k-rpm tachometer, and gauges for oil pressure, water temperature, voltage, and fuel level. The digital odometer has 56k miles, approximately 1k of which were added during current ownership.
The 6.2-liter LS3 V8 was modified by Callaway with an Eaton Roots-style TVS2300 supercharger, an intake manifold with an integrated air-to-liquid intercooler, a high-volume fuel pump and injectors, and an auxiliary fuel pump controller. The carbon-fiber injector covers feature Callaway branding and Reeves Callaway’s signature. The oil was changed in July 2021. A 2015 dyno sheet is provided in the gallery.
Power is sent to the rear wheels through a six-speed manual transaxle and a limited-slip differential. Additional underside photos are presented in the gallery below.
