| | Super COPPERMIX The Super COPPERMIX Clutch is a single clutch system that includes a line-up of standard specification products that can handle outputs of upto approximately 380 horsepower. It employs a COPPERMIX disc and aluminium cover combination that allows for stable transmission and cooling performance. Based on an evaluation by NISMO, it was decided that a larger Ø240 size disc would be employed to prevent the drop in performance that occurs when a smaller diameter disc is placed under a high load. The Super COPPERMIX is equipped with a lightweight flywheel, manufactured from chromoly, which provides the ideal weight to ensure torque. *Service parts are also available.
