JHM Lightweight Aluminum Flywheel for (fits B6 S4 as an upgrade and must use B7 clutch) 05.5 and up B7 S4
JHM 12.97 @ 109.1 all motor and Bolt-on parts quarter mile pass VIDEO -->HERE> NOTE: This flywheel will not work properly on a B6 S4 without the appropriate pressure plate like in the JHM B6/B7 S4 Clutch/Lightweight Flywheel Combo Kit. If you already have a clutch not from us contact us so we can help determine if it will work with this flywheel. Even if you have a B7 S4 and bought a clutch elsewhere this may also not work, some companies sell the weaker B6 pressure plates to B7 owners since they have not done the research JHM has done. Also JH Motorsports has seen many B6 S4 flywheels fall apart causing major damage to the transmission in some cases. This is why JHM built all its clutch and flywheel products around the new and updated B7 style flywheel and pressure plate. This way we can update all B6 owners to B7 spec components. SPECS - 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. 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.
