Check Out the Updated Specter Werkes Corvette GTR

Michigan based tuner, Specter Werkes, has added a custom cam design with more lift which has liberated an extra 80hp (60kW) over the outgoing model, bringing the output to a total of 615hp (459kW) and 578lb-ft (783Nm) of torque.

Specter Werkes is offering many different levels of engine upgrades. The version pictured features a newly displaced 6.8L LS3 engine (factory = 6.2L). Additionally, this Corvette GTR is fitted with a Corsa exhaust, full widebody kit, broadened suspension and a wider covering.

This version also features:

• Special Forgeline VR3P wheels, measuring 19in up front and 20in in the rear
• 285/30ZR19 front and 335/25ZR20 rear Michelin Pilot Sport 2 Zero Press tires
• Stop Tech 15in slotted brake discs and six pistons up front mate with 14in and four piston calipers in the rear
• Painted in BASF liquid silver color (the same used on Mercedes Benz AMG models)
• Interior gets GTR-standard embroidered seats and Spinneybeck leather trim details.

All GTRs are custom-built to order and carry documentation and identification to that effect. Importantly, the upgrades are available across the Corvette range, including the base Coupe, new Grand Sport, Z06 and even the ZR1. Also, note that the BASF liquid silver paint will cost you $5,000 alone.
