We are pleased to finally announce our 2-Piece Rotor 4-Pot 2-pot BBK that will fit most of the popular Lexus vehicles from the 90's through present day.

These kits utilize the latest patented technology from RB Performance Brakes to deliver a light, versatile and affordable braking upgrade while also keeping long-term replacement costs affordable.

Kit contains

  • 4 Two-piece center-mount open slot rotors
  • 2 4-Piston aluminum calipers front
  • 2 2-Piston aluminum calipers rear 
  • 4 Aluminum adapters made of 7075-T6 Alloy (stronger and stiffer than 6061-T6)
  • 1 Set (2 Pair) of stainless steel brake lines
  • 2 Set of RB ET300 street brake pads Front and Rear


  • Rotors
    • Front 360mmx32mm
    • Rear 330mmx24mm
    • 2-Piece fully floating center-mounted rotors allow free rotor thermal expansion
    • Rotors are a special alloy iron material that is heat-treated for uniform micro grain structure. This process and material are the key to the highest level of braking performance and wear characteristics.
    • Aluminum center hats are EDP coated for protection.
    • Rear Hats feature a exclusive bi-metal cast iron sleeve for parking brake retention.
    • Convergent vane design
    • Patent Pending Open-Slot design combines slotted and vented rotor properties without the crack prone stresses involved with these 2 processes.
    • DACRO coated 10.9 fasteners on rotor ring to hat interface held in tension to allow floating under expansion loads
  • Caliper
    • 4-POT front and 2-POT rear Forged 6061-T6 weighing only 5.5/4.5lbs
    • Direct Bolt-on fitment
    • 7075-T6 Mount brackets are CNC machined and EDP coated
    • Low profile design for more wheel fitment options. 
    • 38mm internal seal piston is thermally vented to reduce heat transfer 90% over Aluminum pistons commonly used in BBK calipers. This means longer times at the track and less heat conduction into the brake fluid.*
    • Powdercoated finish in red, black and hard anodize options
    • Uses Standard FMSI pads (D1371 and D1383 ) making replacement pad options vast.
    • Tethered EPDM bleeder cap means no more lost bleeder caps.
    • Made in the USA , Designed fully assembled and 100% hydro tested prior to shipment in Fullerton,CA. Canada shipments are tax exempt due to NAFTA guidelines.
  • Pad Options
    • ET500/300-Street
      • Low dust and virtually noise free.

The ET Series compounds provide excellent modulation, consistent friction and torque output, and can be run from ambient temperature, even during cold winter mornings.


ET300: Performance Street - Delivers braking performance beyond stock pads, yet with minimal dust and no squeaking


ET500: Aggressive Street - Provides additional stopping power over ET300; low dust and little to no squeaking.
