2013 Chevrolet Corvette Grand Sport Coupe - LS3 / Cam / Long Tubes / Forgestar Wheels

This 2013 Chevrolet Corvette Grand Sport Coupe is a sharp, tastefully modified C6 finished in Cyber Gray Metallic over Ebony leather. With just 42k miles, Grand Sport wide-body styling, LS3 power, performance upgrades, Forgestar wheels, Morimoto LED lighting, and upgraded interior/audio equipment, this Corvette delivers the right mix of modern performance, aggressive looks, and everyday usability.

The C6 Grand Sport already starts as one of the best-looking and best-performing Corvette packages of its generation. With wider fenders, functional brake cooling ducts, upgraded suspension tuning, larger brakes, and the naturally aspirated LS3 V8, the Grand Sport gives you Z06-inspired presence with the comfort and convenience of a street-friendly coupe.

This example takes that formula further with a revised camshaft, AirAid intake, long-tube headers, custom ECU calibration, and valved mufflers, giving the car more sound, more response, and a much more aggressive personality than stock.

Exterior

Finished in Cyber Gray Metallic, this Grand Sport has a sinister, modern look that works perfectly with the wide-body C6 lines. The Grand Sport package adds wider front and rear fenders, additional brake cooling ducts ahead of the rear wheels, and a more aggressive stance than a standard Corvette.

Exterior upgrades include Morimoto LED headlights, fog lights, side markers, and taillights, giving the car a cleaner and more modern appearance. The car also features a removable roof panel, front splitter with supports, polished quad exhaust outlets, and painted side mirrors.

The Cyber Gray paint paired with black wheels and LED lighting gives this Corvette a very clean, understated, and performance-focused look.

Wheels & Stance

The car rides on black Forgestar F14 wheels, measuring 18 inches up front and 19 inches in the rear. They are wrapped in Continental ExtremeContact tires sized 255/40 front and 355/30 rear, giving the car a wide, planted stance and plenty of rear tire under the Grand Sport bodywork.

Braking is handled by Grand Sport performance hardware, including six-piston front calipers and four-piston rear calipers over ventilated rotors measuring 14 inches front and 13.4 inches rear. The rotors and brake pads are said to have been replaced in preparation for sale.

The Grand Sport also features model-specific stabilizer bars, stiffer springs, and revised shock absorbers compared with the standard Corvette, giving it a more capable and responsive driving feel.

Interior

Inside, the cabin features Ebony leather bucket seats with a driver-focused cockpit layout. The car is equipped with Keyless Access, cruise control, side airbags, dual-zone automatic climate control, and a removable roof panel for open-air driving.

Interior upgrades include a Sony touchscreen infotainment system, Kicker Audio speakers, and an aftermarket carbon fiber steering wheel with a blue centering stripe. The steering wheel frames the factory instrumentation, including a 200-mph speedometer, tachometer, and supporting gauges for coolant temperature, oil pressure, voltage, and fuel level.

The left seat cushion bolster is flattened, and a replacement cushion is included with the car. Some steering wheel button functions do not currently work. The removed factory steering wheel and factory stereo are also included in the sale.

Engine & Performance

Power comes from the legendary 6.2L LS3 V8, upgraded with a revised camshaft, AirAid intake system, long-tube exhaust headers, and a custom powertrain ECU calibration. These upgrades sharpen the personality of the LS3 and give this Grand Sport a more aggressive sound and stronger performance feel.

The LS3 is one of Chevrolet's most proven modern performance engines, known for its reliability, broad torque curve, and excellent aftermarket support. With the cam, intake, headers, and tuning, this Corvette has the right modifications to make it feel and sound like a serious performance car.

The exhaust system is equipped with valved mufflers, allowing the car to deliver a more aggressive tone when desired. The catalytic converters have been removed from the exhaust system.

Drivetrain

Power is sent to the rear wheels through a six-speed automatic transmission and a 2.73:1 limited-slip differential. The automatic gearbox makes the car easy to drive in traffic while still delivering strong acceleration when called upon.

The limited-slip rear differential helps put the LS3's power to the ground, and the Grand Sport chassis gives the car the wide, stable feel that makes these C6 models so enjoyable.

The Drive

This Grand Sport has the right feel for someone looking for more than a stock Corvette. The cammed LS3, long-tube headers, intake, tune, and valved mufflers give it the sound and attitude buyers want, while the automatic transmission, climate control, removable roof panel, and upgraded infotainment keep it comfortable and usable.

The Forgestar wheels, wide Continental tires, upgraded lighting, Grand Sport brakes, and factory wide-body stance give the car a modern performance look with real capability to match.

With 42k miles, a clean Carfax report, spare parts, and tasteful upgrades, this 2013 Chevrolet Corvette Grand Sport Coupe is a strong choice for someone looking for a C6 that is already modified, well-equipped, and ready to enjoy.
