Frequently Asked Questions
Will this Clutch Masters part fit my 2007-2014 Mini Cooper S?
That application is listed, but confirm the exact part number, engine, transmission, input-shaft spline, flywheel requirement, clutch stage, disc type, and every manufacturer note before ordering.
Should the flywheel be inspected or replaced with a new clutch?
Yes. Inspect the flywheel for heat damage, cracks, runout, and the correct step or friction surface. Resurface or replace it only according to the clutch and flywheel manufacturer's specifications.
Is a clutch break-in period required?
Follow the current instructions for the exact clutch. Many street friction materials require controlled engagement cycles before full-torque use, while some race systems have different procedures.
Installation Instructions
Follow the current Clutch Masters and factory service instructions for this exact part number. Verify every interface before transmission removal, inspect and measure the flywheel and release system, replace worn seals and bearings, keep friction surfaces clean, use the specified fasteners and torque sequence, bleed hydraulic components, confirm release travel, and complete the required break-in procedure before full-torque use.
