Coppermix Clutch Disc Set

This kit includes two Coppermix clutch discs, an aluminum clutch cover, a lightweight flywheel, and an aluminum center plate, as well as flywheel bolts and an OEM release bearing. The Super Coppermix Twin Plate Clutch boasts a 225mm disc outer diameter and is designed to handle substantial power outputs, rated up to 493 kW (670 ps). It features a push-type clutch cover generating 9807 N (1000 kgf) of pressure. The kit's total weight is 15.34, a reduction from the OEM weight of 17.12, contributing to improved vehicle dynamics. Owners should be aware that due to the performance-oriented design, including the sports clutch disc and lightweight flywheel, the transmission or bearings may transmit a rumbling noise, particularly at idle or during acceleration/deceleration around 2000rpm. This noise is inherent to the performance enhancement and does not affect the quality or functionality of the clutch. Additionally, the use of a large operating cylinder is not recommended, as it may lead to misshifts due to insufficient stroke volume. This clutch kit is specifically designed for the following Nissan models: 180SX RPS13 SR20DET (covering various model years from 1991 to 1998), Silvia PS13 SR20DET (1991-1993), and Silvia S14 SR20DET (1993-1998). Compatibility is confirmed for JDM cars only, and buyers are advised to conduct their own research to ensure fitment before purchase.
