SPECS
- ALUMINUM FLYWHEEL USA MADE - These JHM aluminum lightweight flywheels weigh less than 1/2 the weight of stock! 13lbs versus 26.5lbs for B7 S4 (B6 S4 weighs 26lbs). These are a direct replacement for 05.5 and up B7 S4s and an upgrade for 04-05 B6 S4s. The iron friction liner is replaceable, so, you will never have to buy a new flywheel again, you can just swap the liner if you ever replace your clutch. The crank position ring is welded to the ring gear while being retained and fastened with countersunk screws (not cheap pins prone to shearing like some other brands). For those concerned about the driveability and the infamous "chatter" of a lightweight flywheel that Audi enthusiasts have experienced with smaller 4 cylinder and 6 cylinder turbo engines here is the truth. With the B6/B7 S4s 4.2L V8s torquey nature the driveability is very close to stock and the noise is minimal when it is bogged under 1500 rpm. Some of JHMs customers have reported that they did not notice it at all. An added bonus to this upgrade for the B6 S4 owners is that with this flywheel you can now run a B7 RS4 pressure plate that is in our JHM clutch kit. The higher clamp load pressure plate is not compatible with the OEM B6 flywheel, so you must run a JHM lightweight flywheel or a B7 S4 OEM flywheel.
- 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 B6/B7 S4 could dish out. The pressure plate testing allowed us to find that the B7 RS4 pressure plate was the same as the B7 S4 and had 400 more pounds of clamp load vs. the B6 S4 pressure plate. So this is another reason why we highly recommend our full combo if you have a B6 S4. 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 feel.

 

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). For Stage 4 clutches the procedure is the same but you must do this break in procedure for 750 miles. Due to Kevlar's resistance to wear it takes longer to break in. You also MUST avoid any racing activities, launching or aggressive driving that gets the clutch hot during this period.

 

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.
