PROUDLY DESIGNED AND BUILT IN THE USA

In stock and ready to ship as of 12-8-10.

FINALLY a low cost front BB (Big Brake) solution for your B5 S4 that uses the popular Porsche Cayenne caliper that bolts right to your stock spindle with NO MODIFICATIONS! Only minor clearancing of the spindle for the rotor. NOTE: These rotors require the use of Cayenne 6-piston 330mm brembo calipers to do this conversion. The price on this page is only for the rotors. We sell optional hardware and brake lines to make the swap easier as well.

Stock 321mm vs. JHM 350mm 2-piece for the Porsche Cayenne Caliper
-Rotor OD: Stock = 321mm(12.6"), JHM = 330mm(13") - .4" larger
-Rotor Thickness: Stock = 30mm(1.18"), JHM = 32mm(1.26") - thicker
-Rotor Weight: Stock = 21lbs(each), JHM = 19.5lbs(each) - 7% LIGHTER, 1.5lbs less each
-Rotor Cooling Air-gap: Stock = 11mm(.433"), JHM = 15.5mm(.610") - LARGER for better cooling
-Rotor Cooling Center Fin Design: Stock = Straight Fin, JHM = Airfoil - MORE EFFICIENT for better cooling
-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 with NO brackets. All you need is some bolts, nuts, brake lines and JHM rotors and you have a 350mm BBK. Being that it is an OEM part they are readily available and can be found used for great prices.

INCLUDES: 2 - JHM 2-piece Lightweight Slotted Front Rotors. (Each rotor weighs 1.5lbs less than stock for a total of 3lbs weight savings.) 7% lighter!

OPTIONS:
-Use drop down box to select if you need a hardware kit for the calipers (bolts, washers and nuts).
-Use drop down box to select if you need stainless brake lines that adapt these calipers to the B5 S4.

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 B5 S4 with a Cayenne caliper bolted on. 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.
