Due to popular demand, all 2-piece, lightweight rotors will now come with black anodized rotor hats featuring Type 3, hard anodizing, the highest quality and hardest anodizing available for aluminum. This will make the rotor hats more resistant to fade and wear and will hide brake dust better. Due to popular demand all lightweight rotor rings will also feature zinc plating. This high-quality coating will slow the effects of corrosion and keep your rotor rings looking good through the winter.

These rotors shave 21 lbs of unsprung weight from the front of your car while increasing braking performance, they bolt on just like stock! This is a great alternative to a full-on Big Brake Kit since the stock B9 S4-S5-SQ5 rotor is already a stout 350mm (13.8") 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 at a 1/4 of the price or less of a full Big Brake Kit.

Stock vs. JHM
-Rotor Weight: Stock = 27.7lbs(each), JHM = 17lbs(each) - 38% LIGHTER, over 10.5 lbs less each
-Rotor Cooling Air-gap: Stock = 16.15mm(.635"), JHM = 18.5mm(.728") - LARGER for better cooling
-Rotor Cooling Center Fin Design: Stock = Straight, JHM = Airfoil - MORE EFFICIENT for better cooling
-Rotor OD: Stock = 350mm(13.8"), JHM = 350mm(13.8") - SAME
-Rotor Thickness: Stock = 34mm(1.34"), JHM = 32mm(1.18")
-Bolt pattern: - SAME (fits like an OEM rotor would)
