JHM - Lightweight Flywheel (Chrome - Moly Forged) and Clutch Combo for B7 RS4

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. Use dropdowns above to choose.

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.

Features:

• Chatter Free
• Easier engagement from a stop compared to aluminum
• Improved Engagement and momentum when Launching
• One-piece Chromium Molybdenum forging is stronger and more durable than billet steel, aluminum or cast iron.
• Tough, precision-made and dynamically balance
• Lighter and stronger than stock flywheels
• Integral ring gear is induction-hardened for maximum gear life
• Material is properly distributed for strength, greatest heat dissipation and reduced inertia
• CAD-designed, CNC-machined and computer balanced for quality and precision
• Improved throttle response and acceleration

SPECS

- CLUTCH - These JHM Stage 3 (hybrid Ceramic/Metal Backed Organic) street performance clutches (choose stage below before ordering) are from a result of actual on car testing (video proof above) and from pressure plate clamp load testing that JHM had performed on all the available pressure plates for the B6/B7 S4 and RS4. Most of the on car testing was to find the optimal materials for the most streetability while delivering the performance any Naturally Aspirated B7 RS4 could dish out. As for driveability the hybrid combination of materials has made the clutch hold better and handle higher heat as well while still being smooth enough for every day driving with a stock like pedal fee

Why a lightweight flywheel? Well when you reduce the weight of the rotating mass on the engine you free up horsepower. So that is the great benefit of a lightweight flywheel, plus the JHM unit is less expensive than a brand new OEM flywheel and it doesn't have a dual mass setup that can wear out or fail.

INSTALLATION AND TORQUE NOTES HERE

NOTE: Clutch break in is important and must be done properly. For the Stage 3 clutches you need to drive as much city type driving as you can for the first 500 miles (each time you start from a stop or shift it aids in break in, Highway mileage does not count). 

NOTE: For those that are looking for a more robust, race oriented clutch setup we highly recommend looking into our R-Series line-up that does not have an SAC. The SAC in OEM and other aftermarket pressure plates work great for comfort and OEM-like drive-ability, however it is not designed to take excessive abuse of track days or aggressive street driving. We have done rigorous testing since 2012 to develop the ultimate clutch solution for both street and track and the R-Series is what is needed to take these cars to the next level.
