Clutch Masters lightweight steel flywheel for the turbocharged 1.6L Mini Cooper S and John Cooper Works, including the JCW Clubman, Coupe and GP. CNC-machined from 1045 steel billet on Haas lathes in the USA, then zero-balanced and black-oxide coated for rust protection. Reducing rotating mass sharpens throttle response and cuts turbo lag. SFI 1.2 certified and ready to pair with a Clutch Masters FX-series single- or twin-disc clutch.
