In stock and ready to ship.
WHY PAY $750 TO $900 FOR A COMPLETE NEW SET OF FRONT ROTORS FOR YOUR B7 RS4 WHEN YOU CAN BUY THIS KIT AND REUSE THE ALUMINUM HAT YOUR CAR COMES WITH???
Shaves 8lbs of unsprung weight from the front of your car while increasing braking performance, plus they bolt on just like stock! This is great alternative to replacing your complete rotor with OEM parts when your aluminum hat is reusable. You save between $300 and $450 with our kit! We also do away with the annoying crack prone holes and sell these either totally plain or with slots (use drop down box below)

ONLY AVAILABLE SLOTTED: Our slotting is quiet and not noticeable.
Outer ring specs:
We worked closely with a race 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 B7 RS4.
NOTE: With the installs we have done we have found that our slot design is whisper quiet.

Please note: JH Motorsports does not recommend using EBC brake pads with our 2-piece lightweight rotors. Customer have reported and we have found EBC pads leave excessive pad deposits that can cause brake pulsation. Many EBC pads have a break in coating that reacts with the zinc plating used on our rotors
