Description
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.
Included:
1x JHM Chrome-Moly Forged Lightweight Flywheel
1x OEM Pilot Bearing (Pressed Into Flywheel)
10x OEM Flywheel Bolts
NOTE: Flywheel to Crankshaft bolts must be torqued to 65 ft-lbs with the use of Loctite on the threads
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 everyday 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.
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 the break-in, Highway mileage does not count).
