Clutch Masters 02-06 Mini Cooper S 1.6L Supercharged FX300 Clutch Kit Sprung Disc
A heavily modified R53 Cooper S, with a reduced pulley, tune, head work or a bigger supercharger setup, can overpower the factory clutch and even a mild street upgrade. Clutch Masters FX300 kit 03050-HDTZ-D is built for that car: a street clutch for the 2002-2006 supercharged Mini Cooper S that holds 110 percent more than stock while still driving like a normal car in traffic.
The FX300 uses the same Power Plus I heavy-duty pressure plate as the milder Clutch Masters stages, but the disc is different. Its steel-backed Kevlar lining is cut into segments rather than a full ring. With less friction area pressed by the same plate, each square inch sees more clamp pressure, and that is how the FX300 reaches its 110 percent holding increase without moving to a harsh ceramic puck disc. The Kevlar is non-abrasive, so it is easy on the flywheel.
Clutch Masters targets the FX300 at highly tuned naturally aspirated engines and medium-boost turbo or supercharged setups, which describes a well-built supercharged Cooper S. The maker says it has only slightly increased pedal pressure, long life and positive engagement. Two cautions from the maker: it is recommended for the street, not track use, and it needs a minimum 500-mile break-in.
Load the car in fourth gear at low rpm and go to full throttle. If the tach jumps ahead of the speedometer, the clutch is slipping. Then confirm it is not a hydraulic fault by checking for a soft pedal, a leaking slave cylinder or a pedal that does not return fully, and look for oil on the bellhousing, which can make any disc slip. Our slipping diagnosis guide covers these checks step by step.
Not sure you need this much clutch? If your car only has light bolt-ons, the FX200 version is rated at 70 percent over stock with a full-face Kevlar disc and the smoothest feel Clutch Masters offers. Our manual transmission repair cost guide also helps budget the whole job.
Clutch Masters lists 03050-HDTZ-D for the 2002-2006 Mini Cooper S with the 1.6L supercharged engine. The base Cooper and the turbocharged 2007-up Cooper S are different applications. If you own a later supercharged convertible or a car with a JCW package, send us the year and VIN and we will confirm it first.
This is the -D version, with a dampened (sprung) disc that the maker designs for an aftermarket single-mass flywheel. If you are reusing the factory flywheel, Clutch Masters specifies the rigid-disc 03050-HDTZ-R instead. Match the part number to the flywheel you will run, and browse more options in the rebuild kits collection.

No. Clutch Masters designs the FX300 for the street, with only slightly increased pedal pressure and positive engagement. It is the track use the maker advises against, not daily driving.
Clutch Masters lists 2002-2006 Mini Cooper S with the 1.6L supercharged engine. It does not fit the base Cooper or the 2007-up turbocharged Cooper S. Send us your VIN if your car is a later convertible.
Yes for this -D version. Clutch Masters designs its dampened disc for an aftermarket single-mass flywheel, and no flywheel is included. If you keep the factory flywheel, order the rigid-disc 03050-HDTZ-R.
Clutch Masters requires at least 500 miles of break-in for the FX300 so the segmented Kevlar lining fully seats against the flywheel and pressure plate. Avoid launches and full-throttle shifts until then.
Choose the FX200 for bolt-ons and the smoothest feel; it holds 70 percent over stock. Choose the FX300 for a heavily tuned or higher-boost car; it holds 110 percent over stock.
