Kits are designed to provide an overall weight reduction with substantially improved stopping power over the OE brakes in a compact package that fits inside 15'' wheels as used on all street/stip category cars. Forged Billet DynaPro four piston radial mount calipers and PolyMatrix ''E'' compound brake pads are used to generate big stopping power with ultimate resistance to fade at high temperatures. Forged aluminum hats mount 11.75'' diameter rotors with the choice of either a 3/8'' steel or .810'' wide vented iron rotor, based on overall car weight and speed. The kits require no modification to the OE spindle or steering linkage, and are fully compatible with the output of the OE master cylinder.
