The SPEC Stage 2 clutch is a premium, no compromises heavy-duty clutch upgrade for the 2001-2006 E46 M3 (manual transmission). Where the stock clutch is well-known for premature wear when driven hard and the factory dual mass flywheel is a known failure point, the SPEC clutch delivers with an over-engineered, performance-oriented clutch solution. The single carbon-Kevlar clutch is rated at 545 ft-lbs, more than enough for the naturally-aspirated S54 engines. A heavy-duty pressure plate and throw-out bearing complete the package.

The stock clutch in the S54 cars is not a terrible clutch and it is not under-rated (it's the same clutch disc used in the E39 M5). Our tuned M3 street and race cars have used the stock clutch with almost 400hp with only the occassional slip. But if the clutch is not grabbing like you want it to, or your tuning plans will include forced induction, a heavy-duty clutch is what will be needed. The SPEC Stage 2 clutch consists of a carbon-Kevlar friction material paired with a heavy-duty pressure plate. The clutch is stronger and grabs harder than the factory clutch. It has a much more robust feel and engagement. And with this specification the clutch will never be a weak point. The SPEC clutch is designed to work with the stock dual mass flywheel or the SPEC single-mass flywheel (steel or aluminum).

The real weak point in the driveline is in the flywheel. The stock dual-mass flywheel has rubber damper discs inside that will wear out over time. Heat and aggressive driving will accelerate their wear. Even if the clutch contact surface is not showing wear the inner rubber linings most likely are. On most clutch replacements we strongly advise getting a new flywheel at the same time to avoid duplicating the work. You can use the SPEC clutch with the stock or SPEC flywheel. Both the SPEC steel and aluminum flywheels are lighter than stock and will be single-mass. There will be a lot more noise and 'gearbox chatter' with the aluminum but the tradeoff is a much better acceleration and quicker revving. For daily driver commuting you will probably be happiest with the stock flywheel. For the ultimate in sports car feel use the aluminum. For the best of both worlds select the SPEC steel flywheel. It will not fail like the dual mass design but still has enough mass to dampen most engine vibrations.

SPEC Clutch is one of the premier clutch and flywheel suppliers to the tuner market. They are often found on the most highly tuned import and domestic vehicles. They are recent players in the German car community with a special focus on the newer turbo BMW models with high torque output. SPEC has been proven time after time to provide superior performance, drivability, and longevity to the most hardcare enthusiasts around the globe.
