Zip Corvette's gold foil covers will protect your C5 or C6 Corvette's ball joint and tie rod boots from burning up under excess brake rotor heat. The ball joints on 1997-2013 Corvettes are not available without buying the entire lower control arm assembly and the steering knuckle assembles. These covers will protect the boots from melting and protect the ball joint itself from un-wanted rotor heat. A must have for any Autocross, HPDE, or road race where aggressive brake pads are being used. Gold foil covers are precut for an exact fit and have an adhesive backing to hold them in place. Set of 8 covers.
