{"product_id":"coppermix-clutch-disc-kit","title":"Coppermix Clutch Disc Kit","description":"The Nismo Super Coppermix Twin Plate Competition Model Clutch Kit is a specialized, push-type clutch assembly engineered for high-performance Nissan Skyline engines, including the RB20DET, RB25DET, and RB26DETT. The complete kit includes an aluminum clutch cover, a lightweight flywheel, two Coppermix clutch discs, an aluminum center plate, OEM release bearing, and flywheel bolts. By utilizing a lightweight flywheel and advanced disc materials, this system delivers significantly improved response and can handle an allowable output of 544 kW (740 ps).\n\nDue to the specialized nature of this competition-grade clutch and its high-pressure setting, heavy pedal operation is expected, and it is not recommended for general-purpose street use. Transmission or bearing rumbling noise may be audible during idling or at low RPM ranges (around 2000rpm) due to the lightweight design; this is a normal characteristic and does not indicate a performance or quality issue. To maintain optimal operation, it is recommended to avoid excessive half-clutch engagement.\n\nCompatibility is specific to JDM vehicles, including Nissan Skyline ECR33 (RB25DET), HCR32\/HNR32 (RB20DET), and BNR32 (RB26DETT). Importantly, this kit must not be used with a big operating cylinder, as this may cause a misshift due to insufficient stroke volume. Professional installation is recommended, and users should perform their own fitment research prior to purchase as JDM-specific compatibility is not guaranteed for all markets.","brand":"Nissan","offers":[{"title":"Default Title","offer_id":52663127572792,"sku":"3002A-RR593-C","price":1729.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687516743.png?v=1784324087","url":"https:\/\/store.motormia.co\/products\/coppermix-clutch-disc-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
