Description
 
This rear big rotor kit is exclusively developed by RB for upgrading your rear rotors to 365x28mm (from OE 335x20mm) with an extended bracket for an instant track duty BBK.

This rear BBK will convert your rear brake to be exactly same as Model S rear with the following advantage:

  • Oversize w/o over-weight: No weight penalty even with 45mm (1.8") increase in rotor diameter and 8mm in thickness - See weight comparison below - same weight as M3 (Perf), saves 2 lbs for M3 (base)
  • Fits under 18" wheels
  • For more track oriented M3P it also converts the "unusual" OE caliper to "common" rear caliper w/ePB for easy maintenance and pad replacement.
  • It's a standard S rear caliper & pad so never have to worry about the parts supply.
  • You can count on RB for after-service - The most trusted, knowledgeable, and innovative brake company in the performance industry.Rotor Material: Racing Formula Alloyed Gray Iron & Heat treated
  • Comparable front brake upgrade option to match with this rear BBK (365x28mm):
1. 355x32mm rotor kit with model S 4 pot caliper - Your brake set up will be same as Model S and Camaro SS (10-15)

2. 370x34mm rotor kit with Camaro ZL1/CTS-V 6 pot caliper - Your brake set up will be same as Camaro ZL1/CTS-V

3. 380x32mm rotor with RB HD 4 pot caliper for the best balanced brake system.

This rotor kit includes:

2 ea - RB 2pc rotors
2 ea - 1pc caliper bracket (TS11-B) and hardware
1set - RB XT910 street performance pad

Please Note:
Model S rear calipers are required to complete the installation which are not included in the price, but can be purchased from Tesla dealer or eBay (see reference links below)

Reference forum discussion:
I wish Tesla had used a more common rear caliper/pad on the P3D.

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. 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.
