ACT offers several varieties of clutch kits for the MINI Cooper S R53 that provide increasing levels of performance enhancement. Each level of ACT clutch has its purpose, and we can recommend an ACT package for your MINI Cooper S R53 based on the level of modification and purpose of the car. All ACT clutch kits for the 02-06 MINI Cooper S include the friction surface, pressure plate, throw-out bearing, and alignment tool. All ACT Clutches for the MINI Cooper R53 that have a sprung hub require the ACT lightweight flywheel. Picture above is of the MM clutch and for reference only.

 

The "HD" in the part numbers refer to Heavy Duty Pressure Plate. The ACT Heavy Duty Pressure Plate is an excellent combination of increased torque holding and pedal feel for most daily driven cars. The HD pressure plate provides 20%-50% increase in clamp loading while creating only a moderate increase in pedal feel thanks to ACT's special, single diaphragm design. Pedal feels stock to moderate.

 

 

BM2-HDMM: Modified Street Disc - ACT's Modified Street friction surface is SFI certified and is an excellent choice for lightly modified, street driven cars. The MM disc provides quicker engagement than a stock surface and is quiet compared to other, more aggressive, friction surfaces. The sprung hub uses bushings and cone springs similar to OEM clutch discs. This creates frictional dampening which improves clutch life and reduces noise.

 

 

BM2-HDSS: Performance Street Disc - ACT's Performance Street friction surface is SFI certified and is an excellent choice for modified, street driven cars and race cars. The SS disc provides quicker engagement than a stock surface and is quiet compared to other, more aggressive, friction surfaces. The sprung hub uses bushings and cone springs similar to OEM clutch discs; this creates frictional dampening that improves clutch life and reduces noise. Must use ACT flywheel with sprung hub discs; SS, G6 and G4 discs are sprung centered for noise reduction on solid ACT flywheel. Must use ACT Flywheel with sprung hub discs.

 

 

BM2-HDG6: 6-Puck Sprung Race - The ACT 6-Puck Sprung Hub Race Disc is SFI certified, so it is legal for all forms of racing that require SFI compliance. An ACT G6 race disc has a very durable friction surface with good spline life. The G6 was designed for a highly modified car that is drive to, on and from the track, as long as harsher engagement is acceptable. The sprung hub helps to reduce driveline shock and be relatively quiet compared to an unsprung hub, though the G6 can still be noisier than a full face disc and will have some chatter. Must use ACT flywheel with sprung hub discs; SS, G6 and G4 discs are sprung centered for noise reduction on solid ACT flywheel. Must use ACT Flywheel with sprung hub discs.

  

 

BM2-HDG4: 4-Puck Sprung Race - An ACT 4-Puck Sprung Hub Race Disc has very harsh engagement and is designed for road race cars only. A G4 friction surface has good durability and spline life characteristics under normal use. The sprung hub helps to reduce driveline shock and be relatively quiet compared to an unsprung hub but will definitely have chatter. The ACT G4 is SFI certified, so it is legal for all forms of racing that require SFI compliance. We do not recommend the G4 for a street driven car. Must use ACT flywheel with sprung hub discs; SS, G6 and G4 discs are sprung centered for noise reduction on solid ACT flywheel. Must use ACT Flywheel with sprung hub discs.

 

BM2-HDR4: 4-Puck Solid Race Disc - The ACT 4-Puck Solid Hub Race Disc is legal for all forms of racing that require SFI compliance. The biggest benefit of the ACT 4-Puck Solid Hub Race Disc is its extremely fast shifts thanks, in part, to its reduced inertia. An ACT R4 race disc friction surface has good durablity but will have shortened spline life. ACT designed the R4 for a heavily modified drag race or road race cars where extremely harsh engagement and clutch chatter is expected. We do not recommend the R4 for any road going car.
