Clutch Masters 21-22 BMW G80 M3/G82 M4 S58 6-Speed FX1000 Race Twin Disc Clutch Kit
If your 2021 or 2022 BMW M3 (G80) or M4 (G82) with the six-speed manual has started to slip on a hard pull, or you have tuned the S58 well past stock and the factory clutch cannot keep up, this is the race-level answer from Clutch Masters. Part number 03240-TDKR-A is the FX1000 twin disc: a 10.00 inch (254 mm) two-disc clutch packaged with a flywheel, built for big power that still sees street miles. This is not a mild upgrade. It belongs in a car with a serious tune, larger turbos or regular track and drag strip days.
In the standard M4 the S58 twin-turbo inline-six makes about 473 hp and 406 lb-ft, and in North America the six-speed manual was offered only on the standard M3 and M4, because the Competition models came with the automatic. A tune adds a large amount of torque on top of that, and a single-disc clutch can only hold so much before it slides. The FX1000 splits the clamp load across two friction discs, which roughly doubles the friction area without needing a bigger diameter. Clutch Masters uses a strap-driven plate design so engagement stays smooth with little chatter, while the unit still survives hard launches, clutch kicks and high-rpm shifts. Clutch Masters lists this kit in its Twin Disc 1000 Series, the line aimed at drivers who want the most from a high-power car.
A slip test is quick: in a high gear at low speed, go to full throttle and watch whether rpm climbs faster than road speed. Before blaming the disc, check the hydraulics for a leak at the bellhousing, a soft pedal or a pedal that does not return fully, since any of those can hold the clutch partly released. Also be honest about how the car is driven. Clutch Masters says its torque ratings are ballpark estimates, and that driving style and purpose matter as much as peak power. If the car is mostly driven on the street with a moderate tune, the Factory Fit FX250 twin disc or the Factory Fit FX350 may suit it better. Our manual versus automatic repair cost guide helps you budget the labor.
This kit is listed for 2021 and 2022 BMW G80 M3 and G82 M4 models with the S58 engine and the six-speed manual. It does not fit cars with the automatic transmission, and it is not for the xDrive Competition models, which were not sold with a manual. Production changes inside a model year do happen, so confirm your car is a six-speed manual and send us the year and last 7 of the VIN if you want us to check it before you order. Other clutch, flywheel and rebuild parts are in our rebuild kits department.

Only if the car has the six-speed manual. In North America the Competition models were sold with the automatic only, so this kit is for the standard manual M3 and M4.
Yes. Clutch Masters describes the FX1000 03240-TDKR-A as a twin disc clutch kit and flywheel, so the clutch is matched to the flywheel in the box.
Clutch Masters requires a minimum of 500 miles of normal stop-and-go driving, with no full-throttle shifting or compression braking, before the clutch sees full abuse.
The FX1000 is the race-level kit for very high power and hard launches. If the car is a street car with a moderate tune, a Factory Fit FX250 or FX350 is usually the better match for drivability.
Twin disc units often make some light noise from the intermediate plate when the pedal is down. Clutch Masters uses a strap-driven plate design to keep engagement smooth and chatter low.
