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 treated
Machining: Open Slot
Surface: EDP Coating w/cross cut grinding on friction surface
Replacement Ring: D601-05-381
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.

- Alloyed iron formula adds strength and heat resistance. Heat
treating further improves rotor performance for a more uniform and
cooling vanes are of a convergent nozzle design, which increases airflow and
turbulence and makes discs cooler. (Illustration #1)
The center-mount flanges for hat mounting to the rotor ring have several
benefits. (Illustration #2)
Exclusive full floating design with 10.9 grade alloyed hardware.
Hardware is DACRO coated and crimp locking. DACRO is highly corrosion
resistant and provides a film for easier movement between the hat and rotor ring
as disc expands and contracts and
the crimp design provides positive engagement without rattling or torque loss
- It allows the ring to be used on either side of the vehicle simply by mounting
the hat on either side of the ring (unidirectional).
- The stress load transferred from the ring to the hat is balanced.
- Air inlets are widely open to both
inboard and outboard sides of the rotor. More air suctions and even
temperature on both sides of the disc surface.
- Heat transfer from the disc surfaces to the hat is even and minimized by
increasing the flange length and the airflow around the flanges.
- Mounting flanges are on both friction surfaces ultimately provides
