JHM B7 RS4 CHROME-MOLY FORGED SINGLE-MASS LIGHTWEIGHT FLYWHEELS AVAILABLE NOW!!
NOTE: This is now an option you can choose instead of our traditional Alumimum Flywheels.
The Chrome-Molly Forging allows fewer opportunities for failure and promotes uniform, efficient heat transfer from the clutch disc. This is to prevent warped friction inserts or loose ring gears. It is strategically lightened, stronger, safer and has better thermal capacity than OE cast flywheels. With smooth operation at all RPMs, these flywheels meet the needs of both the enthusiast and the hardcore racer.

Introducing the JHM R Series Clutch Kit for the B7-RS4!!!
**NOW FEATURING OUR NEW STAGE 3R CLUTCH DISC!!!**
Since 2010, we have been working on developing a proprietary performance clutch kit for the B7-RS4. After years of research, prototyping, and in car abuse we are proud to release the JHM R Series Clutch Kits! Our R Series Pressure Plate and Stage 5 R Disc were featured in our customer's record setting quickest and fastest B7-RS4 with our RS4 Supercharger Kit:
Our years of research and development of this clutch kit have led to the creation of our JHM R Series Pressure Plate. This pressure plate is a non-SAC (self-adjusting clutch) style pressure plate. This allows to run a set of more aggressive discs to hold more power and withstand even more abuse. For example, the shock that our proprietary ceramic 6-puck disc would put on the OEM B7-RS4 pressure plate would destroy the SAC.
The diaphragm on our R Series Pressure plate is a custom design that we worked for years to get just right for the B7-RS4 and B6-B7 S4s. We designed it specifically for these cars and their throwout bearings. We did not simply take another pressure plate that works in another brand car and try to make a "band-aid" solution with spacers or other shortcuts to make the pressure plate work for an Audi.
- 43% increase in clamp load torque holding capacity over the already stout B7-RS4 Pressure Plate.
- The stiffness of the clutch pedal is increased by about 25%.
- Better clutch pedal control and modulation is achieved through our spring design.
- The spring pressure is much more linear not peaky like the B7-RS4 pressure plate making the clutch pedal behavior more predictable in the uptake of the pedal and engagement point of the clutch disc.
- Thicker pressure plate straps increase the longevity and durability of the Pressure Plate.
- The JHM R Series Pressure Plate has been designed to work with our JHM Lightweight Flywheel so any RS4 customer with our current clutch kit will be able to upgrade to the R Series by just purchasing the clutch disc and pressure plate - not the entire Flywheel and Clutch Combo.
- JHM R Series Clutch Kit (Clutch Disc and Pressure Plate): Our R Series Clutch Kits feature your choice of 2 different clutch disc materials: Stage 1 R is a performance organic disc and Stage 5 R is a 6-puck disc featuring our proprietary ceramic material. You can chose your clutch disc material from the drop down menu below. We recommend our Stage 1 R Performance Organic Clutch Disc to those looking to get the best compromise between daily driveability and torque holding capacity. Our Stage 3 R disc offers the ultimate combination of daily driveability, torque holding capacity, and durability for back to back to back pulls. Our Stage 5 R Clutch Disc is the ULTIMATE clutch disc for your B7-RS4. The Stage 5 R is a 6-puck clutch disc featuring our proprietary performance ceramic material making it the most aggressive clutch solution that we offer to date. This is clutch disc that we are currently running in our in-house B7-RS4 AND that was featured in our customer's B7-RS4 that set the world record time for the fastest and quickest B7-RS4 (see video above). This clutch disc can REALLY hold some power!

INSTALLATION AND TORQUE NOTES HERE
NOTE: Clutch break in is important and must be done properly. All R Series Clutch Discs have a break in period of 500 miles. This means that you need to drive as much city type driving as you can for the first 500 miles after the disc is installed. Each time you start from a stop or shift, it aids in break in of the clutch material. Highway mileage does not count. You MUST avoid any racing activities, launching, or aggressive driving that gets the clutch hot during this period.
