The ZR1 Corvette front splitters look great but they can dramatically increase the downforce on your C6 Corvette's front end. Zip recommends installing a factory-style bumper reinforcement when purchasing a ZR1 style front splitter for your Corvette. The ZR1 Corvette bumper reinforcement mounts behind the Corvette's front bumper and supports the lower air dam. It can be used with C6 Z06 and Grand Sport Corvettes or C6 Corvettes with a Z06/GS body update package
