Frequently Asked Questions

Will this Clutch Masters part fit my 1975-1978 BMW 530i Base?
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.
