It’s been almost a year since Specter Werkes released their C6 Corvette GTR, now the Michigan-based car tuning specialists has delivered a new Corvette GTR. Starting off with the factory Chevy model, Specter Werkes used their imagination and taste to create a unique Chevrolet Corvette GTR supercar, with custom bodywork and performance tuning. The LS3 engine was increased in displacement from 6.2 liters to 6.8 liters, and with a new cam shaft design, performance numbers were increased to 615 hp and 578 ft lbs of torque. There are several levels of engine tuning that Specter Werkes can perform, and this model received the most basic tune. Underneath the Corvette GTR is fitted with a Corsa performance exhaust system, while receiving a complete wide body makeover for the exterior.
