E46 330i SPEC Stage 1 Performance Clutch Kit

The SPEC Stage 1 clutch is a premium, no compromises SPORT clutch upgrade for the 2001-2003 E46 330i/ci (5-speed 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 430 ft-lbs, more than enough for a naturally-aspirated M54 engine. A heavy-duty pressure plate and throw-out bearing complete the package.

The stock 330 clutch was not designed for performance. It works fine for a daily driver street car with no mods but performance and longevity quickly drop off when adding more power or using the car for aggressive street, autocross, or track use. A lot of our customers also hate the self-adjusting clutch (SAC) mechanism and the clutch delay valve that makes clutch engagement inconsistent and unnatural feeling. It's no wonder that for the Grand-Am Cup touring car races the rules specified an E36 M3 clutch! If you're unhappy with the stock clutch feel or your future plans include additional upgrades that boost torque, then a heavy-duty clutch is what will be needed. The SPEC Stage 1 clutch consists of a hybrid carbon-Kevlar and organic 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 with a lightweight aluminum single-mass flywheel.

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 an aluminum flywheel. A machined steel flywheel is also an option as a middle ground. 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.

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.
