Clutch Masters 14-19 Mini Cooper S 1.5L Turbo FX250 Clutch Kit w/ Aluminum Flywheel
A tuned third-generation Mini with a six-speed manual is hard on the factory clutch and dual-mass flywheel. If your 2014-2019 Mini is slipping in third and fourth after a tune, or the dual-mass flywheel has started to rattle and you want it gone, Clutch Masters 03465-HD0F-AK is the FX250 single-disc kit paired with a 14 lb lightweight aluminum flywheel. It is part of the Clutch Masters line for the 1.5L turbo (B38) cars, where the kit converts the car from a dual-mass to a single-mass flywheel.
The FX250 pairs the Clutch Masters Power Plus I heavy-duty pressure plate with a mixed-material disc. The side of the disc facing the pressure plate uses Fiber Tough friction material, and the side facing the flywheel uses steel-backed organic. That combination is meant to hold more torque than a full-face Kevlar disc while keeping engagement close to stock. Clutch Masters rates the FX250 system at 110 percent more holding capacity and aims it at street drivers and weekend racers who drive hard on a regular basis.
The aluminum flywheel is the big change. It weighs 14 lb and has a Type 3 hard anodized finish. Replacing the factory dual-mass unit removes rotating mass, so the engine revs up and drops between shifts faster, and it removes a part that wears out and gets expensive. The tradeoff is that a single-mass flywheel no longer absorbs firing pulses, so expect more gear rattle at idle and more vibration at low rpm, especially on a three-cylinder. Our dual-mass vs single-mass flywheel guide explains that tradeoff in detail.
Do a full-throttle pull in fourth from low rpm and watch whether rpm climbs without matching road speed. Check that the clutch fluid is full and clean first, since a weak hydraulic system can mimic slip or cause drag. For dual-mass rattle, listen at idle with the pedal up and then pressed; a change points at the flywheel. The slipping diagnosis guide and our dual-mass flywheel failure guide cover both checks.
Our listing covers the 2014-2019 Mini F-series with the manual transmission, titled as Cooper S 1.5L turbo. Be careful here: in the US the 1.5L three-cylinder B38 is the Cooper engine, while the Cooper S uses the 2.0L B48. Clutch Masters lists 03465-HD0F-AK in its 1.5L turbo conversion group, and lists its separate 2.0L kits for the Cooper S, Clubman and Countryman. Check the engine code on your registration or send us your year and VIN before ordering. If your car is a 2.0L Cooper S, see the 2.0L FX250 rigid disc kit 03460-HD0F-R. If your 1.5L car is stock or lightly modified, Clutch Masters also makes an FX100 version with the same aluminum flywheel as a softer step; ask us about availability. More kits are in our clutch and rebuild kit department.

Probably not. Clutch Masters files 03465-HD0F-AK under its 1.5L turbo conversion kits, and the 2.0L B48 Cooper S has its own kits such as 03460-HD0F-R. Check your engine code or send us your year and VIN and we will confirm.
Usually some. A single-mass aluminum flywheel does not damp engine pulses, so expect more gear rattle at idle and more vibration at low rpm. Most owners accept it for the faster rev response and the end of dual-mass flywheel replacements.
Clutch Masters publishes the FX250 as having 110 percent more holding capacity than stock and aims it at street cars driven hard. The company says driving style and use matter more than a torque number, so tell us your mods if you are unsure between FX100, FX250 and higher stages.
The kit includes the pressure plate, disc, aluminum flywheel, release bearing, fork, alignment tool and hardware per Clutch Masters. Plan on new flywheel bolts, fresh brake fluid for bleeding, and a rear main seal if it shows any seepage while the transmission is out.
Yes. Clutch Masters requires a minimum of 500 miles of normal stop-and-go driving with no full-throttle shifting or compression braking before you drive it hard.
