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.
FINALLY a low cost front BB (Big Brake) solution for your C5-A6-S6 or allroad with the 4.2L V8 that uses the popular Porsche Cayenne caliper that bolts right to your stock spindle with NO MODIFICATIONS! NOTE: These rotors require the use of Cayenne 6-piston brembo calipers to do this conversion. The price on this page is only for the slotted rotors only. We sell optional hardware and brake lines to make the swap easier as well. If you are interested in our FULL BBK, please see that product page back in this section. Stock 345mm(S4) vs. JHM 350mm 2-piece for the Porsche Cayenne Caliper
-Rotor OD: Stock = 345mm(13.6")S4, JHM = 350mm(13.8") - .2" larger
-Rotor Thickness: Stock = 30mm(1.18")S4, JHM = 32mm(1.26") - thicker
-Rotor Weight: Stock = 25lbs(each)S4, JHM = 17lbs(each) - 32% LIGHTER, 8lbs less each
-Rotor Cooling Air-gap: Stock = 9.5mm(.374")S4, JHM = 18.5mm(.728") - 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)
NOTE: For the A4s their rotors are even smaller so this upgrade would be even more substantial. 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 8lbs less than stock for a total of 16lbs weight savings.) 32% lighter! This is with a larger and thicker and rotor than stock(S4) to work with the Cayenne caliper! OPTIONS:
- Go back one section if you need a hardware kit for adapting the calipers to your car (bolts, washers and nuts).
- Go back one section if you need need stainless brake lines that adapt these calipers to the C5-A6-S6 or allroad with the 4.2L V8. Click to enlarge picture

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 C5-A6-S6 or allroad with the 4.2L V8 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. Click to enlarge picture
INSTALLATION NOTES AND PICTURES HERE
NOTE: The C5 A6-S6 4.2l V8 spindles sometimes have excess material where the caliper mounts to the spindle at the upper mount point. This takes the caliper out of parallel to the rotor. Check for this by installing the caliper and rotor with no pads and checking that the outer pins are the same distance from the rotor (make sure you have the rotor flat and installed with 5 bolts). If the top pin is much closer or touching you need to shave down the upper mounting point until the caliper is parallel with the rotor. Also you will notice that the caliper is closer to both outer pins vs the outer pins, this is ok and as designed. This outward bias is there to give max clearance for the rotor from the spindle and for optimum performance. Unfortunately this is a mass produced cars and inconsistencies do happen from time to time in the manufacturing of a car. This is a quick fix and once the caliper is parallel the kit will install easily.
Note - This brake upgrade only fits under most 18" wheels or larger. It fits stock 18" C5-A6-S6 or allroad with the 4.2L V8 wheels with a 3mm wheel spacer.
