Description
 
nother valuable BBK exclusively developed and offered by RB

  • 100% bolt-on installation, easier than installing stock rotors.
  • Fully compatible between pad and rotor w/o compromising the fitment and performance even it's a retrofit kit.
  • Designed and built by the most experienced brake mfgr with track proven record in various tracking communities; from small race cars like Miata MX5, S2000, WRX to super muscle monster cars like GTR, Mustang GT350, Porsche 911, Camaro Z28/ ZL1, Corvette Z06/ZR1 and dodge Challenger Hellcat etc...

Rotor kit includes:

  • 2 ea - RB 2pc rotors
  • 2 ea - Caliper spacers

  • 4 ea - Caliper mounting bolts (M12x1.75)
  • 1set - RB XT910 Street (not suitable for tracking) performance pad (a $200 value)

Additional pad sets and track compounds can be purchased here:

Due to the original caliper/pad are designed for 320mm rotor, as a result of geometry (rotor diameter) change, the stock pad will have about 4-5mm above the rotor edge which is not recommended.



RB kit includes a modified pad (PD968M) which will fit the bigger rotor just like OE pad would.


With RB BBK, you are not only upgrading the rotor, but
"pad & rotor" together, so your braking power will increase as it should be instead of just bigger rotor but compromising to a smaller pad like competition's kit.

Surface: EDP Coating w/cross cut grinding on friction surface
Material:

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

Design:

  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.
