Distinctive designStyling that accents the Corvette�s design is a hallmark of Specter Werkes/Sports and the C6 GTR takes that philosophy to the next level, with a completely redesigned body. Like the original C5 GTR, the C6 version is based on widened bodywork that supports the larger wheel/tire combination. It also gives the car a more aggressive stance � as do the racing-inspired front and rear fascias.
The GTR�s design sharpens and embellishes many of the Corvette�s design cues, but doesn�t eliminate them. It is a design that respects and celebrates the Corvette�s design heritage, by building on it to suit the taste of decerning individuals... the Specter Werkes' customer � enthusiasts in search of a unique and exclusive vehicle.
At 77 inches, the GTR�s bodywork is 4.5 inches wider at the rear fenders (2.25 inches per side) than a regular-production C6 Corvette and 1 inch wider than the Corvette Z06. The physical difference may seem small, but the overall effect, along with a slightly longer overall body length, creates a unique proportion to the GTR that is aggressive and suggests speed even when stationary.
Specter Werkes/Sports replaces the front and rear fenders; front and rear fascias; doors, rocker panels and hood � everything except the roof panel and rear hatch � with special, hand-formed GTR panels. Each car is completely repainted and re-assembled with the new bodywork at Specter Werke�s Troy, Mich. facility. A bold, LED-lit rear center-mounted stop lamp is integrated in the rear fascia. It was originally designed for the Cadillac CTS, and gives the GTR an unmistakable rear appearance.
GTR #1C6 Corvette GTR #1 is powered by Specter�s emissions-legal Matrix II engine package for the LS3 engine. It is a �stroker� engine package that boosts displacement from 376 cubic inches (6.2L) to 416 cubic inches (6.8L). That is achieved with a Callies 4340-forged crankshaft that delivers a 4.00-inch stroke. Forged rods from Manley and forged pistons from Mahle round out the rotating assembly.
The camshaft is a special grind from Comp Cams and the LS3 heads� combustion chambers were enlarged from 71cc to 72cc in order to maintain an 11:1 compression ratio. With stainless steel long tube headers and a low-restriction air intake, the engine is rated at 535 horsepower and 530 lb-ft of torque. The engine also features carbon fiber fuel rail covers and a yellow-painted intake manifold.
The Matrix II LS3 channels power to the pavement via HRE wheels, measuring 19 x 11 inches in the front and 20 x 12 inches in the rear. They wrapped with Michelin Pilot Sport 2 Zero Press tires (285/30ZR19, front, and 335/25ZR20, rear). Behind the wheels are StopTech brakes, featuring ST60 six-piston calipers and 15-inch slotted rotors in the front and ST40 four-piston calipers and 14-inch slotted rotors in the rear. The calipers� yellow color contrasts with the HRE wheels� black center sections. The GTR also features Hotchkis adjustable stabilizer bars.
On the outside, C6 GTR #1 is painted a gorgeous BASF liquid silver color, the richness of which appears wet to the touch. It is a premium color choice and represents the nearly unlimited paint options available to customers. Inside, GTR-standard embroidered seats and Spinneybeck leather trim details contrast elegantly with the Corvette�s black interior. A Specter Werkes/Sports production plaque is mounted on the center console.
GTR LegacyThe Specter Werkes/Sports GTR was first launched a decade ago and saw the creation of nearly 30 specialized cars that were delivered across the country � including the two most notable GTRs, which were created for Dale Earnhardt Sr. and Jr., in 2001.
