ACT 01-06 BMW M3 E46 XT/Perf Street Sprung Clutch Kit
The ACT BM9-XTSS is a street clutch for the 2001 to 2006 BMW M3 (E46) with the 3.2L S54. It suits owners whose original clutch is worn out or slipping, and especially cars with supercharger kits or other big power adders where the factory clutch is no longer enough. It keeps an organic disc, so the M3 still drives smoothly in traffic, but the Xtreme pressure plate adds a large margin of clamp load.
BM9-XTSS pairs ACT's Xtreme pressure plate with the 3000815 Performance Street sprung disc. ACT rates the kit at 549 ft-lb at the crank, 79 percent over the original clutch. That is far beyond what a stock S54 makes, which is why the kit makes sense on forced-induction builds that still see daily miles. The organic lining has a high copper content for heat transfer and a steel backing for burst strength, with reduced marcel for quicker shifts. The disc is 240 mm (9.4 in) on a 1.375 in input shaft.
Kit contents per ACT are the B015X Xtreme pressure plate, the 3000815 sprung disc, the RB1401 release bearing, the PB1002 pilot bearing, the AT25 alignment tool and M8-1.25 x 20 mm pressure plate bolts. The flywheel is not included. ACT states the kit must be used with an ACT flywheel for proper clearance with the sprung hub, and lists the 601010 XACT Streetlite and 601015 XACT Prolite flywheels for this car.
Rule out the hydraulics first: a spongy pedal, a sticking clutch delay valve or a leaking slave cylinder can feel like a clutch problem. Check for oil at the bellhousing, since a rear main seal leak will soak a new disc. Then do a roll-on in fifth from about 3,000 rpm; if the tach rises ahead of road speed, the clutch is slipping. Our slipping diagnosis guide covers the test.
ACT lists BM9-XTSS for the 2001 to 2006 BMW M3 (E46) with the S54 3.2L straight-six, including Euro-market E46 M3s. It does not fit the 323i, 325i, 328i or 330i, which use different engines and clutches. ACT does not separate six-speed manual and SMG cars in its listing, so if your M3 has SMG, send us your VIN and we will confirm fitment before it ships. Shipping weight is about 13.8 lb. More parts are in our rebuild kits category.
For a lighter pedal, compare the BM9-HDSS Heavy Duty street kit. It uses the same disc type with a Heavy Duty plate and suits stock or mildly modified S54 cars.

No. It is listed only for the 2001 to 2006 M3 with the S54 engine.
It will work, but the pedal is noticeably heavier than stock. If the car is stock or close to it, the Heavy Duty BM9-HDSS gives a lighter pedal with plenty of margin.
