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. Coupled with the Heavy Duty pressure plate, this kit provides a clamp load increase of 35%. Recommended for light to moderately modified Mini Coopers who want to run the stock flywheel. Torque capacity is rated at 338ft/lbs at the crank.

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. Coupled with the Heavy Duty pressure plate, this kit provides a 35% increase in clamp load. The sprung hub uses bushings and cone springs similar to OEM clutch discs; this creates frictional dampening that improves clutch life and reduces noise. The HDSS kit is suggested as a stock replacement or for light to moderately modified Mini Coopers, but requires a solid flywheel as this is a sprung hub kit. Torque capacity is rated at 338ft/lbs at the crank.

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. Suggested for high modified or dedicated track Mini Coopers running a solid flywheel. Torque capacity is rated at 432ft/lbs at the crank.

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. Suggested for highly modified or dedicated track Mini Coopers running a solid flywheel only. Torque capacity rated at 432ft/lbs at the crank.

The reduced inertia of the ACT 6-Puck Solid hub allows for very fast shifts at the expense drivability. An ACT R6 race disc friction surface has very good durability but will have shortened spline life. ACT designed the R6 for a highly modified track cars where harsher engagement is expected and some clutch chatter is not a problem. The 6-puck layout of the R6 will absorb, and dissipate, more heat than a 4-puck unit. The ACT 6-Puck Solid Hub Race Disc is legal for all forms of racing that require SFI compliance. Suggested to heavily modified or dedicated race Mini Coopers running the stock flywheel only. Torque capacity rated at 432ft/lbs at the crank.

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. JSC does not recommend the R4 for any road going car. This kit is a solid hub design so it is compatible with the factory Mini dual mass flywheel. Suggested for heavily modified or dedicated tack Mini Coopers only. Torque capacity is rated at 435ft/lbs at the crank.
