The ACT Solid Hub 4-Puck Clutch Kit Mini Cooper S 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.
Mini Coopers come from the factory with a dual mass (or sprung) flywheel and a solid hub clutch. If you have previously upgraded to a solid disc flywheel, you will need to purchase a sprung hub clutch to maintain proper clutch operation. If you are planning on using your ACT clutch kit with your factory flywheel, a solid hub disc is required. Please let us know what kind of flywheel you will be pairing with your clutch kit so the appropriate style disc can be ordered.
