Shaves 13lbs 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 a full on Big Brake Kit since the stock C5 RS6 is a stout 365mm (14.4") and most may not want to spend $2,000 plus for a full Big Brake Kit. We basically brought the same high performance great cooling designed rotor to these drop in (fit like stock) front rotors and at a 1/4 of the price or less of a full Big Brake Kit.

Fitment:
-Direct Replacement for OEM #4B3 615 301E for the Left Front & 4B3 615 302A for the Right Front

Stock vs. JHM
-Rotor Weight: Stock = 27.5lbs(each), JHM = 21lbs(each) - 24% LIGHTER, 6.5lbs less each
-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 = 365mm(14.4") - SAME
-Rotor Thickness: Stock = 34mm(1.34"), JHM = 34mm(.1.34") - SAME
-Bolt pattern: - SAME (fits like an OEM rotor would)
