Rotors utilize SVS420JZ material that is highly rust-resistant and compatible with all types of disc brake pad material including sintered metal. Each rotor is surface induction hardened, and then precision machine ground for trueness and computer-controlled machine punched for accurate center-to-center hole dimensions. The rotors are drilled in a full sweep pattern to provide superior heat dissipation and consistent performance wet or dry.
