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

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.

A lightweight flywheel was manufactured from chrome-molybdenum to obtain the ideal weight to ensure torque.

The flywheel is provided with a special aluminum cover with exceptional heat-radiating properties.

The center plate is equipped with a special strap function^*1 that backs up smooth gear disengagement by preventing blockage.
