The strongest single clutch: one that can handle the 420ps, SR20DET engine but is still easy to operate. This was the development concept for the SUPER COPPERMIX.
[ With an allowable torque of 54 kgf·m, this is the strongest single clutch ]
Allowable dynamic friction torque: 54 kgf·m (static friction torque: 81 kgf·m) Handles an estimated maximum allowable power of 420ps
This is a single clutch system that takes "the ease of use" and "high power handling" fortes of COPPERMIX to the next level. This series also includes a lineup of standard specification products that can handle 380ps.
* measurements for NISMO standards are fixed with an SR20DET engine tuned to high-power specifications
Employs the industry's first large-diameter 240 size disc
The 240 size COPPERMIX disc together with an aluminum cover maintain stable transmission and cooling performance. After an analysis conducted by NISMO of several different models, including those of other companies, it was decided that using a 240 size disc would prevent the drop in performance that occurs when a small diameter disc is placed under a high load. High power single clutches from other companies combine a pressure cover with a small diameter disc probably because they just divert a disc from their multi-plate clutch and set it at a high load. NISMO specifically chose a 240 diameter to get maximum durability and ease of use.
Lightweight Flywheel
A lightweight flywheel was manufactured from chrome-molybdenum to obtain the ideal weight to ensure torque.
Aluminum Cover
The flywheel is provided with a special aluminum cover with exceptional heat-radiating properties.
Center Plate with Strap Function
The center plate is equipped with a special strap function*1 that backs up smooth gear disengagement by preventing blockage.
| *1 | This mechanism incites the pressure plate inside the cover to disengage from the disc using the force exerted by the strap plate. It has become part of the standard installation for all NISSAN vehicles with manual transmissions. |

- 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.
- Do not use the SUPER COPPERMIX with a Big Operating Cylinder. This can result in blocking proper disengagemnt of the gears because of insufficient stroke volume.
