Clutch Masters 01-05 BMW M3 3.2L E46 FX100 Clutch Kit w/Steel Fly
Clutch Masters 03CM2-HD00-SK is an FX100 clutch kit with a single-mass steel flywheel for the E46 BMW M3 with the 3.2L S54 and six-speed manual. It answers the two problems that hit almost every aging E46 M3 at once: a disc that has started to slip under hard acceleration, and a factory dual-mass flywheel that rattles, clunks or has worn out its springs. One kit replaces both.
Clutch Masters rates the FX100 at 70 percent more holding capacity than stock. It uses the Power Plus I heavy-duty pressure plate and a steel-backed organic disc with a Marcel spring wafer, which keeps engagement smooth and pedal effort only slightly above factory. It is meant for street cars with intake, exhaust or tune work, not a supercharged S54.
The steel flywheel replaces the dual-mass unit. A single-mass flywheel has no springs to wear out, so it does not develop the free play that makes an old dual-mass flywheel knock. Steel keeps more inertia than an aluminum flywheel, so the car is easier to pull away from a stop, but expect somewhat more gear rattle at idle than with a fresh dual-mass. The kit also includes a release bearing, pilot bearing where used, alignment tool, instruction card and decals. Shipping weight is about 29 pounds.
On an E46 M3 the clutch and flywheel are easy to blame for noises that come from elsewhere. Clunks on and off throttle can also be the driveshaft flex disc, center bearing or differential mounts, so inspect those first. For slip, floor it in fourth at around 2,500 rpm and watch whether the tach runs ahead of road speed; our slipping diagnosis guide explains what to look for, and shift flare vs. slip covers how to tell the two apart.
Our listing covers the 2001-2005 BMW M3 3.2L E46 with the six-speed manual. Clutch Masters' chart for 03CM2-HD00-SK lists the 2001-2006 E46 M3 six-speed and the SMG car. If you have an SMG M3 or a 2006 model, send us your VIN before ordering so we can confirm. The part number is specific to the S54; it does not fit a 325i or 330i. Other E46 M3 choices in our rebuild kits and clutch section include the stronger FX300 sprung-disc kit for heavily modified cars.
While the gearbox is down, the flex disc and center bearing are right there. A flex disc and center bearing kit is worth checking against your car, and owners who track the car often step up to a DSS carbon fiber driveshaft.

Yes. The SK suffix means a Clutch Masters single-mass steel flywheel is included, and it replaces the factory dual-mass flywheel.
Our listing covers 2001-2005 E46 M3 six-speed cars. Clutch Masters lists 2001-2006 and the SMG car on its chart; send us your VIN for a 2006 or SMG car.
Expect a little more gear rattle at idle than with a fresh dual-mass flywheel. Steel keeps more inertia than aluminum, so it is still easy to drive in traffic.
Clutch Masters rates it at 70 percent more holding capacity than stock, meant for bolt-ons, tunes and small nitrous shots, not forced induction.
The kit includes release and pilot bearings. Check the rear main seal, fork and pivot, flywheel bolts, the driveshaft flex disc and center bearing, and bleed the hydraulics with fresh fluid.
