Clutch Masters 14-18 BMW F80 M3/F82 M4 S55 6-Speed FX1000 Race Twin Disc Clutch Kit w/o Flywheel
An F80 M3 or F82 M4 with the six-speed manual makes serious torque from the twin-turbo S55, and once a tune, downpipes or a bigger turbo setup go on, the factory clutch is often the first thing to give up. Clutch Masters 03795-TDKR-X is the FX1000 Race twin disc for these cars: two ceramic friction discs in a strap-driven assembly, sold without a flywheel. If your M3 or M4 flares rpm on a hard third-gear pull, slips in fourth on the highway, or smells hot after a track session, this is the top of the Clutch Masters range for the S55 manual.
A twin disc clutch puts a floater plate between two friction discs, so the pressure plate clamps four friction faces instead of two. That doubles the working surface without needing a bigger diameter, which is how a kit can hold far more torque than stock while still fitting behind the factory bellhousing. On the 1000 Series, Clutch Masters uses the TDKR code for a race pack that pairs a sprung ceramic disc with a rigid ceramic disc. The sprung disc takes some of the shock out of driveline engagement; the rigid disc keeps the stack thin and aggressive. The pressure plate and floater are strap driven, which is what keeps engagement controlled on a race clutch rather than grabby. Expect more pedal effort, sharper engagement and some chatter or rattle at idle compared to the stock setup. This is a race-stage kit, not a soft daily-driver upgrade.
Do a high-gear slip test first: about 30 mph in fourth, then full throttle, and watch the tach against the speedometer. If the needle climbs while the car does not, the clutch is slipping. Before you spend this much, rule out the hydraulics. Air in the line or a tired slave cylinder can leave the clutch partly released and mimic a worn disc, so bleed the system and recheck. Our slipping diagnosis guide covers how to separate clutch slip from other driveline problems, and the manual vs automatic repair cost breakdown shows where clutch labor money goes so you only pull the gearbox once.
This listing is for the 2014-2018 F80 M3 and F82 M4 with the S55 3.0L and the six-speed manual. The Clutch Masters product page lists 03795-TDKR-X for the 2014-2018 M3 (3.0L F80 6-Speed) and the 2014-2019 M4 (3.0L F82 6-Speed), so 2019 M4 manual owners are covered by the maker. It does not fit the seven-speed DCT cars, which use a completely different clutch. The kit ships without a flywheel and must run on the matching Clutch Masters twin disc flywheel, not the factory dual-mass unit. Send us your year and VIN before ordering and we will confirm the flywheel you need. If you want a lighter-duty twin that already includes an aluminum flywheel, see the FX250 SS twin disc for the F80. For a single disc option, compare the FX350 dampened disc kit. Every clutch we carry is in our rebuild kits category.

Clutch Masters lists this part for the 2014-2019 F82 M4 six-speed and the 2014-2018 F80 M3 six-speed. It does not fit DCT cars. Send us your VIN if you are unsure which transmission your car has.
No. This kit is sold without a flywheel and needs the matching Clutch Masters twin disc flywheel. It does not bolt to the factory dual-mass flywheel. Contact us with your VIN and we will confirm the flywheel part number.
It is a race-stage clutch with a sprung and a rigid ceramic disc. Expect firmer pedal effort, sharper engagement and some chatter or rattle. If the car is mostly a street car, a lighter stage such as the FX250 SS twin or the FX350 single disc is usually the better fit.
Clutch Masters asks for at least 500 miles of normal stop-and-go driving with no full-throttle shifts or hard launches before full use, so the friction surfaces bed in evenly.
Inspect the slave cylinder and release bearing, bleed the clutch hydraulics, and check the rear main seal and input shaft seal for leaks while the gearbox is out.
