Clutch Masters 01-05 BMW M3 E46 6sp FX400 Dampened Disc Clutch Kit w/o FW (Use w/ Single Mass FW)
Clutch Masters 03040-HDCL-D is the FX400 eight-puck ceramic clutch for the E46 BMW M3 with the S54 3.2L and six-speed manual, built for cars that already run a single-mass flywheel and now make more power than the factory clutch was sized for. Supercharger kits, turbo builds and serious track use are where this kit earns its place. The listing is the clutch only, without a flywheel, which is why the title says to use it with a single-mass unit.
The S54 leaves the factory on a dual-mass flywheel that damps crankshaft firing pulses with springs between two masses. Once that is swapped for a solid flywheel, the damping has to come from somewhere else. The D in 03040-HDCL-D marks the dampened disc: a heavy-duty sprung hub that takes over that job so the gearbox and driveline are not hit by every pulse.
Clamp load comes from the Power Plus I hi-leverage heavy-duty pressure plate, and the friction side is a segmented eight-puck ceramic button disc. Clutch Masters rates the FX400 system at a 170 percent increase in holding capacity over stock. Of its two FX400 layouts, the HDCL eight-puck is the less aggressive one: Clutch Masters says its full-face ceramic design keeps chatter minimal thanks to the marcel cushion between the linings, and describes it as designed for street-driven cars. That makes it the FX400 to choose for an M3 that still sees traffic, compared with the harsher six-puck disc.
Slip does not set a code on the E46, so test it: warm the car, select fourth at low rpm and roll into full throttle. If engine speed climbs faster than road speed, the clutch is letting go. Rule out hydraulics first by checking the slave cylinder for leaks and bleeding the system if the pedal is soft. Also look for oil at the bellhousing, since a leaking rear main seal will contaminate any new disc. Our slipping diagnosis guide covers the procedure, and manual versus automatic repair cost helps set a budget for the full job.
Our listing covers the 2001-2005 BMW M3 E46 with the six-speed manual. Clutch Masters' chart for 03040-HDCL-D lists the 2001-2006 M3 3.2L E46 six-speed and the 2001-2006 M3 3.2L E46 SMG. If your car is an SMG, or still has the original dual-mass flywheel, contact us with your year and VIN before ordering. This dampened disc is meant for a single-mass flywheel; a car that keeps its dual-mass flywheel normally takes the rigid-hub R version instead.
