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, and an excellent upgrade
for both street and track. 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
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 treatedMachining: Open SlotSurface: EDP Coating w/cross cut grinding on friction surface
NOTE: Retaining and jack screw holes might have been eliminated to prevent the screws from stripping and breaking, causing tremendous effort to remove and replace the rotors. Our two-piece rotor hats are made of aluminum which is easier for installation and removal. See detail view here.
