Corvette Grand Sport by GeigerCars.de

Leave it to the Germans to do American muscle better than the Americans. This time around, tuning house GeigerCars.de has taken on the Corvette Grand Sport and the result begins to encroach on Chevrolet's own Corvette ZR1.

Bolting a supercharger to the 6.2-liter LS3 V8, Geiger has boosted power up from 430 horses to 588. They've also beefed up the transmission, the suspension, brakes, tires and aerodynamics package while they were at it. The result is a 0-60 time of less than four seconds. Which may still fall short of the ZR1's 640-horsepower-driven 3.3-second sprint, but it's still plenty fast enough to challenge Germany's finest.
