Save money and weight by purchasing this complete package that includes: Features and Benefits:
  1. RB discs are curved vane (vs. OE pillar vane) for more efficient cooling.
  2. Our two piece rotor rings are replaceable when worn out, unlike OE you must purchase the whole rotor assembly.
  3. RB rotor rings are uni-directional (same disc can be assembled for either left or right side).
  4. RB rotors are made with better metallurgy and heat-treated, so they are lighter weight than OE and last longer.
  5. Same discs are used in other motorsports heavily tracked cars such as Nissan GT-R, Viper ACR-E and Corvette ZR1 (CCM conversion), so these rotors are used by thousands of track enthusiasts with confidence.
  6. We offer XT910 compound for street driving with low dust and no squeaking, XR70 for dedicated track application.

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.

  4. Iron sleeve insert
RB aluminum rotors hats are constructed of aluminum with an iron sleeve insert. This allows for significant weight savings while still preserving the use of the stock emergency brake. This design is only available through RB.
