Flywheel Notes: A smooth, flat flywheel surface is essential for proper clutch operation. If upon inspection of your Infiniti G37's flywheel there are signs of scoring, heat damage or warpage, the flywheel should be resurfaced or replaced to assure good clutch performance. IF YOUR FLYWHEEL SHOWS ANY SIGNS OF CRACKING, REPLACE IT! If you unsure about the condition of your flywheel, we highly recommend purchasing a Competition Clutch flywheel with your clutch kit. Typically, flywheel resurfacing costs around $80 to $100, but it can be hard to find a quality shop to do it. It is usually almost as cost effective just to purchase a new flywheel.
