NISMO SUPER COPPERMIX TWIN S13/S14

• A super-strong clutch that combines ease of operation with an output ceiling of more than 600ps ̶ 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.
• Allowable dynamic friction torque measured at 84 kgf･m (static friction: 143 kgf･m) Can handle an estimated power of 670 ps
• This multi-plate clutch system takes the “ease of use” and “high power handling” fortes of COPPERMIX to the next level.
• Numerical values are NISMO measurement values standardized using a pushtype clutch combined with an RB26DETT engine.
• Evaluations were based on street and circuit driving. No quarter-mile evaluation was made.
• 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 center 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 chromemo-lybdenum high carbon steel.
• Aluminum cover
• The flywheel is provided with a special aluminum cover with exceptional heat-radiating properties.
• Center plate with special dual-role strap functionality
• The center plate is equipped with a strap function*1 that also prevents any problems with disengagement.
• *1 This mechanism leverages the reaction force accumulated by the strap plate to cause the pressure plate to constantly move away from the disc.
• It is employed as a standard part in manual transmissions and is installed in all production vehicles.
• SPECIAL COMPETITION MODEL
• For high power users we have developed a special SUPER COPPERMIX TWIN as our RACE COMPETITION MODEL.
