This kit includes:

  • 2 ea. One-piece Slotted Rotors
  • 2 ea. 4-Piston calipers (RB4045)
  • 2 ea. Aluminum adapters and hardware
  • 1 Set of RB ET500 brake pads

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.

4-Piston Caliper:

  • Caliper Body: Made of forged 6061-T6. Light weight at only 4.5lbs, these new RB4000 calipers are re-designed and built for the toughest brake jobs with extended service life before any rebuild is required.
  • Low Profile: Together with RB Center-Mount design two-piece rotors, you hardly even need to require a spacer to install the kit. It fits under 16’ wheel for 300mm rotors.
  • Piston Material: Made of stainless steel instead of aluminum commonly used by other caliper mfgrs which can substantially reduce the heat transfer (approx 1/10 of aluminum) from the pad to brake fluid. Pistons are vented to further reduce the heat contact area and improve air circulation thereby reducing more heat transfer. (Image 1)
  • Dust Seal: Our dust seal is of built-in type (instead of external boot type) uniquely designed to shield the dust and foreign material from contamination and will not rip - as commonly seen on boot type dust seals. (Image 2)
  • Hardware: Brake pad pins and banjo connections were re-designed for easier brake line connection and brake pad replacement.
  • Surface Coating: Powder coating with most durable finish for lasting appeal.
  • Hardware: Most hardware is made of stainless steel for durable performance and appearance.
  • Never Get Lost Bleeder Cap: Newly designed with a retaining loop so you will never have to find it again and/replace the lost ones. (made of durable EPDM) (Image 3)
  • Use standard FMSI brake pads (D647): A very common P/N (same as WRX 4-pot fix pistons calipers, plenty of choice for suppliers and compounds.
  • Made in USA: Calipers are designed, fully assembled and hydro-tested in our Fullerton, CA facility, with full after sales support/service.

Adapter: 7075-T6 Aluminum Alloy
