NISMO SUPER COPPERMIX S13/S14

• 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. 
• Allowable dynamic friction torque: 54kgf･m（static friction torque: 81kgf･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 240size disc
• The 240size 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 heatradiating 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.
