Clutch Masters 14-18 BMW M3 3.0L F80 6-Speed FX250 SS Series Twin Disc Clutch w/Alum Flywheel
If your F80 M3 with the six-speed manual has started to flare in the upper gears after a tune, or the factory twin disc is simply worn out, this is the kit most owners look at first. The Clutch Masters FX250 SS Series twin disc, part number 03795-HD0F-DLX, replaces the S55 clutch and flywheel as one matched set. Clutch Masters designed it to sit between the comfortable factory twin disc and its 725, 850 and 1000 Series race kits, so the car keeps its street manners while gaining holding power.
BMW fitted the manual F80 with a twin disc clutch from the factory: two friction discs and a floating plate share the load, which lets a compact clutch hold the torque of a twin-turbo inline six. The trouble starts when a tune, downpipes or charge pipes push torque beyond what that factory unit was rated for. Clutch Masters says its Factory Fit FX twin discs use components similar to the factory layout, with higher-end friction material and lighter parts, built on more than 45 years of clutch work.
The FX250 is the mildest friction stage in that family. On Clutch Masters FX250 discs the pressure plate side runs Fiber Tough friction and the flywheel side runs steel-backed organic. The organic face keeps take-off smooth and progressive, which matters in a car that sees traffic, while the Fiber Tough side adds bite and heat resistance. The kit includes an aluminum flywheel, so the clutch and flywheel are a known matched pair rather than new discs against an old, heat-checked surface.
Run a slip test on a safe road: sixth gear around 2,500 rpm, then full throttle. If revs jump ahead of road speed, the clutch is slipping. Before you blame the discs, check the hydraulics. A weeping slave, air in the line or a pedal that does not return fully can keep the clutch partly released and act just like a worn clutch. Look for oil at the bellhousing drain, too, because a seeping rear main seal will ruin a new clutch in weeks. To budget the job, our manual versus automatic repair cost guide lays out typical labor.
Choose the FX250 for a stock or lightly tuned M3 that is driven mostly on the street. If you are running a bigger tune or regular track days, the FX350 SS Series twin disc is the next step up in the same family. Shoppers comparing brands can also look at the Spec SS-trim twin disc for the S55. Dedicated race and high-horsepower builds belong on the FX1000 race twin disc.
This listing covers the 2014 to 2018 BMW M3 (F80) with the S55 3.0L twin-turbo engine and the six-speed manual. It does not fit cars with the seven-speed M-DCT, which use a different flywheel and no clutch pedal. Clutch Masters also describes this kit for the F82 M4 with the same engine and manual gearbox; if you own an M4, or a car that has been converted from DCT, send us the year and last 7 of the VIN and we will confirm before it ships. More clutch and flywheel parts are in our rebuild kits department.

No. This kit is for the six-speed manual only. DCT cars use a different flywheel arrangement and have no clutch pedal.
Clutch Masters describes this kit for both the F80 M3 and F82 M4 with the S55 and six-speed manual. Our listing is set up for the M3, so M4 owners should send the year and last 7 of the VIN and we will confirm before shipping.
Yes. The kit comes with an aluminum flywheel matched to the twin disc assembly, so you do not need to resurface or reuse the factory flywheel.
It is the most street-oriented stage in the Clutch Masters twin disc range. The organic flywheel-side face keeps take-off smooth, so it feels close to factory in traffic while holding more torque once the car is tuned.
Pick the FX250 for a stock or lightly modified car that lives on the street. If the car has a big tune, upgraded turbos or sees track days, the FX350 adds holding capacity.
Yes. Clutch Masters calls for at least 500 miles of normal stop-and-go driving, with no full-throttle shifting or compression braking, before hard use.
