I'm selling a brand new, never been used or installed JHM Rear Big Brake Kit. My car was totaled before I was able to install it.
Stock vs. JHM
- Rotor OD: Stock B6-B7 S4 = 300mm (11.8 inches) JHM = 330mm (13.0 inches) - More than 1 inch LARGER than stock better braking performance.
- Rotor Weight: Stock = 13.0 lbs (each), JHM = 11.5 lbs (each) - A total of 3 lbs LIGHTER with IMPROVED braking performance.
- Rotor Cooling Air-gap: Stock = 8.5mm (.334 inches), JHM = 13mm (.511 inches) - LARGER for better cooling
- Rotor Cooling Center Fin Design: Stock = Straight Fin, JHM = Airfoil - MORE EFFICIENT for better cooling
- Rotor Thickness: Stock = 22mm (.866 inches), JHM = 22mm (.866 inches) - SAME

-Works with stock sized, replacement B6-B7 S4 rear brake pads. Such as OEM, Hawk, PBR, Mintex, Etc. We sell pads as well, if you don't see the ones you want contact us for details.
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.
Note - This brake upgrade fits under the Stock B6-S4 "Avus" style, 18" inch wheels. It also fits under both stock B7 S4 18" wheel designs. Even more room under most aftermarket 18" wheels and larger.
Asking price is $750. Reasonable offers will be considered.
