Rotor Comparison:

Size (mm) Wt (lbs)
OE 1-PC 320x28 22.5
RB 2-PC 316*x28 14.3

Our rotor dia is sized to properly fit the pad contact to eliminate a lip on the rotor edge after the rotor is worn down instead forming a rusty lip like OE.

Features and Benefits:

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 that delivers 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.

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: Surface Slots or Drill+Slots (No open slots is available)
Surface: EDP Coating w/cross cut grinding on friction surface

Click here to learn how RB two-piece rotors are built differently than the competition.


  1. Alloyed iron formula adds strength and heat resistance. Heat treating further improves rotor performance for a more uniform and stabilized microstructure.


  1. The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler. ( Illustration #1)

  2. The center-mount flanges for hat mounting to the rotor ring have several benefits. ( Illustration #2)
    • 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 excellent heat balance.
  3. 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 at temperature.
