Rear BBK (Big Brake Kit), JHM 330mm for B6-B7 S4

SKU: JHM-BBK-1023x330x22



FINALLY a low cost 330mm Rear Big Brake Kit (BBK) for your B6-B7 S4. This is the BEST Rear BBK we make to compliment our massive 350mm 6-piston Cayenne Caliper BBK we offer for the front. This kit cannot be bought anywhere else since we make the custom, lightweight rotor ring and hat in house. These parts are not available from any other source. Our kit includes a JHM exclusive park brake spring relocation kit to allow the largest rotor possible on a stock wheel. The factory park brake spring limits the rear rotor diameter (it protrudes outboard and would hit a stock wheel on a rotor of this size).

Rotor Ring Specifications:
We worked closely with a racing brake manufacturer that supplies many NASCAR racers and a couple major brake kit companies. Due to their expertise we chose to have them build us the outer rings to our specs to fit the B6-B7 S4. The rotor rings feature 12 attachment points for durability and strength.

Center Hat Specifications:
We CNC machine the Aluminum center hats in house for their recommended materials and thicknesses for durability. 12 attachment points for durability and strength. We also engrave JHM in them in 3 locations equal from each other, it looks clean and doesn't jump out or look tacky.
