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 torqueN.m (kgf.m) - Kinetic friction: 530(54) / Static friction: 794(81) Allowable output kW (ps): 309(420) Clutch cover - Pressure N・m (kgf): 9807(1000) - Type: Push Kit Contents: COPPERMIX clutch disc/ Aluminum clutch cover/ Lightweight flywheel/ Flywheel bolts/ Release bearing (genuine Nissan part)/ Sticker Warning: - The sports clutch discs and light weight flywheels, which are designed and manufactured to increase capacity for higher outputand 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. As for S15　6MT, the Dual mass flywheel (with damper spring) is installed. When clutches are exchanged, the allophone is generated. Because the flywheel of Nismo is a solid type.
