JTC MOTORSPORTS Built this 2008 Grand Sport (Z51) to compete against the amazing ZR1 Corvettes on the track or the street. In this build, we tore out, eliminated all the GM Shocks, Brakes, Torsion Arms, rebuilt the transmission for Power and Performance. The car was lightened up with Carbon Fiber Hood, Hatch Back, Carbon Fiber Skirts and Wing was added. The LS Motor was gone complete through, changing the Cam, Heads and adding Headers. This car not only looks fast and mean, but out handled and Performed better than expected.
