Feature:
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.
-Marries 84 kgf·m of torque with revolutionary ease in shifting-
*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 push-type 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 obtaine 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 specially to fit the new lightweight chrome-molybdenum flywheel. Together they guarantee the ideal weight allowance for the greatest torque.
*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.
Product Warning:
- The sports clutch discs and light weight flywheels, which are designed and manufactured to increase capacity for higher output and to improve clutch response, may cause the transmission or bearings to make a rumbling noise which is not present when using the original Nissan production parts. Such noise is particularly likely to occur when idling or when accelerating and decelerating at around 2000 rpm. Please be aware that this rumbling is not due to any defect in the parts.
- Road-tests have shown that these products outperform G-max types in reducing the rattling sound which is characteristic of six-speed manual transmissions, Getrag-equipped vehicles and S15 6-speed manual transmission vehicles.
- Do not use the SUPER COPPERMIX TWIN with a Big Operating Cylinder. This can result in blocking proper disengagement of the gears becouse of insufficient stroke volume.
