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.

It Shaves 4.5 lbs of unsprung weight from the rear of your car while increasing braking performance, they bolt on just like stock! We brought the same high-performance great cooling designed rotor to these drop-in (fit like stock) rear rotors while saving money over OEM rotors!

Stock vs. JHM
-Rotor Weight: Stock = 13.75lbs(each), JHM = 11.5lbs(each) - LIGHTER,2.25 lbs less each.
-Rotor Cooling Air-gap: Stock = 6.35mm(.250"), JHM = 13mm(.511") - LARGER for better cooling
-Rotor Cooling Center Fin Design: Stock = Straight Fin, JHM = Airfoil - MORE EFFICIENT for better cooling
-Rotor OD: Stock = 330mm(12.9"), JHM = 330mm(12.9") - SAME
-Rotor Thickness: Stock = 22mm(.866"), JHM = 22mm(.866") - SAME
-Bolt pattern: - SAME (fits like an OEM rotor would)
