Even though Specter Werkes first introduced the C6 GTR last summer, they have continued to make improvements to the package. Now that SEMA is just around the corner, the Troy, Michigan-based tuner has unleashed perhaps the best variant yet to the GTR family - this one featuring BASF Blue Pearl paint, HRE Carbon Fiber wheels and a twin turbo LS7 V8 courtesy of Lingenfelter which produces a mind-blowing 800 horsepower. The Specter Werkes GTR Corvette will be prominently displayed outside the Las Vegas Convention Center as a feature car for HRE Wheels.
