RB rotors are made of harder iron than OE rotors. Our rotors are most compatible with semi-metallic brake pads. We do not recommend the use of ceramic brake pads, which may cause vibration.
Rotor Material: Racing Formula Alloyed Gray Iron & Heat treated
These two-piece rotors were engineered to be the best stock replacement two-piece rotor on the performance market. This rotor is direct bolt-on, easy to install, no additional hardware needed. They can deliver consistent brake torque under extreme heat, session after session. When it comes to replacement - operating cost over the time will be lower than one-piece rotor. Our unique and patented rotor designs make our discs cooler and last longer:
