Specter Werkes, the Corvette tuners from Troy, MI unveiled the C6 GTR last summer, but are set to reveal a new and improved version at SEMA next week. Featuring the LS7 V8 with a twin-turbo setup courtesy of Lingenfelter Performance Engineering, this hyper-Vette produces an incredible 800 horsepower. The looks back up the performance, with BASF Pearl Blue paint, HRE CF40 carbon fiber wheels, and Specter’s unique body package for the C6. Other performance upgrades include StopTech brakes front and rear and a Corsa exhaust system.

The car will be prominently displayed outside the Las Vegas convention center in just a few days, so expect plenty of live high-res photos. Until then, hit the jump for the company’s press release and browse the gallery below for an eye-full.
