Due to popular demand, all of our 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 winters.

OEM S4-S5 Rotors vs. JHM Lightweight Rotors (A4-A5 vehicles will yield greater results)
-Rotor Weight: Stock = 23lbs(each), JHM = 24.1lbs(each) - Only 1lb heavier for a MUCH larger rotor
-Rotor Cooling Air-gap: Stock = 11.5mm(.450"), JHM = 18.5mm(.728") - LARGER for better cooling
-Rotor Cooling Center Fin Design: Stock = One Direction Airfoil (one side pumps the air from the inside out and the other side pumps the air from the outside in), JHM = Airfoil (side specific rotors that both pump the air from the inside out) - EQUAL EFFICIENCY for equal cooling
-Rotor OD: Stock = 345mm(13.6"), JHM = 382mm(15.039") - 1.43" LARGER
-Rotor Thickness: Stock = 30mm(1.18"), JHM = 34mm (1.33") - 4mm (.15") LARGER
-Bolt pattern: - SAME (fits like an OEM rotor would)
Why the Porsche Cayenne caliper? With its 6-piston design and MASSIVE brake pads it is a strong performer. Also it bolts right up to your spindles using our JHM CNC'd Caliper Brackets. All you need is the included bolts, brake lines and JHM rotors and you have a 382mm Big Brake Kit.
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 B8 Chassis. 12 attachment points for durability and strength.
Center hat specs:
We CNC machine the Aluminum center hats in house based on their recommended materials and thicknesses for durability. 12 attachment points for durability and strength. We also engrave JHM in them in 3 locations equal from each other, it looks clean and doesn't jump out or look tacky.
Caliper Color Options:
-Factory Porsche Red
-Black
-Yellow
-Blue
NOTE: These come from the factory RED in color with the Porsche logo and this option ships ASAP. Opting for a different color will remove the Porsche Logo and add an additional lead time of 1 to 3 weeks to strip and re-coat the calipers due to the fact they are only available in red from the factory.
NOTE: This brake upgrade only fits under 19" wheels or larger. It fits stock 19" B8 S5 wheels with NO wheel spacer and most other OEM and aftermarket wheels as well.
