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.
