The SR20DET in the S15 Silvia is a high-revving turbo engine with serious performance potential, but the factory clutch quickly becomes a limitation once boost and power levels rise. The NISMO Super Coppermix Competition Twin Plate Clutch Kit is a high-performance upgrade engineered specifically for the S15 Silvia (SR20DET), including both Spec S and Spec R variants. This twin-plate system uses NISMO’s special COPPERMIX friction material on both discs for exceptional heat resistance, strong bite, and noticeably smoother engagement compared to conventional metallic clutches, making it highly drivable even in daily or spirited street use.
The kit includes a lightweight flywheel, aluminum clutch cover, aluminum center plate, and a center hub with built-in damper for refined operation and reduced driveline shock. These components dramatically lower rotational mass, resulting in quicker throttle response, faster rev-matching, and improved acceleration while maintaining excellent durability under high torque. It is a direct fit for S15 models with the 6-speed transmission and has become a popular choice for high-power SR20DET builds pushing well beyond stock levels.
At Terra Firma Automotive, we supply this genuine NISMO Super Coppermix Twin Plate Clutch Kit as a premium drivetrain upgrade for S15 Silvia owners seeking serious horsepower with usable street manners. Developed and tested by Nissan’s performance division, it provides the perfect balance of power-handling capability, refinement, and reliability.
