  • $ 2,03371

Part Number: 2034-311-411
Side: L/R
Position: REAR
Size: 332x24mm (13.1" x 0.9")

This kit includes:
  • 2 Two-piece center-mount rotors
  • 2 4-Piston calipers (RB4045)
  • 2 Aluminum adapters and hardware
  • 1 Set of RB ET300 brake pads

    This kit requires a 17" or larger wheel size.

    Two-piece rotor:
  • True floating two-piece rotors with patent pending center-mount design.
  • Direct bolt on, easy to install.
  • Alloyed iron formula adds strength and heat resistance. Heat treating further improves rotor performance for a more uniform and stabilized microstructure.
  • EDP Coating w/cross cut grinding on friction surface.
  • Cast iron hat to retain the emergency brake use.


  • Piston Material: Upgraded to stainless steel from aluminum that can substantially reduce the heat transfer (approx 1/10 of aluminum) from the pad to brake fluid.
  • Double Sealing System: Our uniquely designed double seals in addition to primary hydraulic seal, the dust seal acts as a secondary back up seal (in case primary seal fail) in addition to its normal dust sealing.
  • Caliper Body: Re-shaped for tougher stiffness and appealing look.
  • Hardware: Brake pad pins and banjo connections were re-designed for easier installation and pad replacement.
  • Surface Coating: Liquid paint is used, which is more resistant to chipping than powder coating.
  • Light Weight: Weighs only 5 lbs. (compared to old CP4 4.75 lbs.), yet this new RB4000 calipers shall offer extended service life before any rebuilt is required.
Adapter: 7075-T6 Aluminum Alloy

Rotor Design:

Our unique and patent pending 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.
