Kit includes:
  • 2 ea. 1pc Brake rotors
  • 1 set Brake pad
Features and Benefits:
  1. Plug and play installation - Made to fit OE calipers without any modifications.
  2. Reduced rotating mass and unsprung weight - Weight savings resulting in better handling and acceleration.
  3. Replaceable disc - Rotor ring can be detached from rotor hat, unlike OE, and replaced separately for overall lower maintenance cost.
Rotor size & weight comparisons:
Weight Comparison
OE 1-piece 24.2 lbs.
RB 2-piece 20.6 lbs.
Weight Savings: 3.6 lbs.

Replacement Components:
Replacement ring: D501-07-381

RacingBrake Makes Me Happy

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:

  1. Convergent vane design

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

  2. Center-mount design

    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. True floating design

    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.
