Stage 1 Performance Clutch Kit offers a nice upgrade from the factory setup for the 'sport minded' MINI driver.

Features an integrally molded carbon-based, high performance organic lining that offers smooth engagement and excellent life. This lining has an integrally molded steel backing for strength under high clamp loads and temperatures. Best for street and limited track/off-road usage.

Stage 2 Performance Clutch Kit for the MINI is a perfect upgrade for the Cooper with some performance modifications and used in an occasional autocross or 'driver education' events.

Features pure segmented kevlar disc with steel backing. This lining features excellent drivability like the Stage 1, but offers slightly longer life and higher torque capacity. Best for street, drag, pulling and autocross.

These plates can feature clamp loads from 20%-40% higher than original equipment and have a very reasonable pedal requirement. The exclusive 360 degree pivot technology assures a perfectly even lift and disc clamp, maximized leverage, more consistent clamp load and minimized wear.

INSTALL NOTES

Unless using a new flywheel provided by SPEC, existing unit must be resurfaced prior to installation of the clutch product to ensure integrity of friction surface. Owner must also break in the new high performance clutch for a minimum of 450 miles, primarily city and/or stop-and-go driving, before full throttle engagement, drag launching or speed shifting. * FAILURE TO EXECUTE EACH OF THE ABOVE WILL HINDER CLUTCH PERFORMANCE AND VOID ALL WARRANTY!!!

Unless otherwise instructed by written notice from SPEC, follow manufacturer’s instructions when installing clutch and flywheel products. SPEC recommends that all bolts be inspected before re-installation, and any bolts that have been removed and re-torqued multiple times replaced. SPEC will not warrant any component failure due to install error.

How to find the right Clutch Replacement for your MINI Cooper
Created: June 19, 2015
Identifying the correct MINI Factory Clutch Kit can be confusing. The part number varies depending on the production year, Cooper or Cooper S, and engine type. The chart below should help you find the correct kit. The clutch on the Mini is designed to function properly at a given horsepower figure (plus some headroom).  As the Mini engine gets upgraded producing more power than stock, the increased horsepower can overpower the stock clutch's clamping force and/or the friction material on the clutch disc.  This can cause excessive clutch slip and the net result is a burnt clutch making the Mini non-operational.
