Select Your Car to Verify Fitment
PROUDLY DESIGNED AND BUILT IN THE USA
**NOTE: As of 8/1/2012, all JHM Lightweight Rotors will now feature zinc plating!!!** This high quality coating will slow the effects of corrosion on the rotor surface and will keep your rotors looking good through the winter!
IN STOCK AND READY TO SHIP AS OF 8-1-12! 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 WHILE ALSO GAINING 15MM IN DIAMETER FOR BETTER BRAKING PERFORMANCE??? Shaves 5lbs of unsprung weight from the front of your car while increasing the diameter of the rotor and 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 upgrade to a 15mm larger rotor for less than heavy stock replacments! We also do away with the annoying crack prone holes and sell these with quiet slots. Stock vs. JHM
-Rotor Weight: Stock = 24lbs(each), JHM = 21.5lbs(each) - 11% LIGHTER, 2.5lbs less each (5lbs total)
-Rotor Cooling Air-gap: Stock = 13mm(.512"), JHM = 18.5mm(.728") - LARGER for better cooling
-Rotor Cooling Center Fin Design: Stock = Straight Fin, JHM = Airfoil - MORE EFFICIENT for better cooling
-Rotor OD: Stock = 365mm(14.4"), JHM = 380mm(15") - 4% LARGER for better caliper leverage on the wheel
-Rotor Thickness: Stock = 34mm(1.34"), JHM = 34mm(.1.34") - SAME

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. Click to enlarge picture
NOTE: With the installs we have done we have found that our slot design is whisper quiet.
