Nismo Super Coppermix Twin Disc Clutch Kit
A super-strong clutch that combines ease of operation with an output ceiling of more than 600hp – this was the development concept that launched the SUPER COPPERMIX TWIN. NISMO first floated this concept as a carbon twin product. Two years into its development, we decided that the low μ of carbon facings could not match the performance that COPPERMIX promised. We spent the next year and a half developing twin discs using COPPERMIX. This makes the SUPER COPPERMIX TWIN the culmination of three and a half years of testing and development. It is the ultimate model in the NISMO multi-plate clutch series.

Center Hub

Using a center hub increases the engagement surface between the clutch disc and the serrated section of the transmission’s input shaft. This lowers the overall pressure on individual splines. It reduces wear to the input shaft and prevents disengagement problems. Having a central hub also makes installation easier than for single clutches by eliminating the risk of damaging the splines or misaligning the 2 discs during clutch assembly.

Lightweight Flywheel

The ideal weight for maximum torque was obtained by using a lightweight flywheel manufactured from specially crafted chrome-molybdenum high carbon steel.

Aluminum Cover and Lightweight Flywheel Set

An aluminum cover with excellent heat radiation was fabricated especially to fit the new lightweight chrome-molybdenum flywheel. Together they guarantee the ideal weight allowance for the greatest torque.
