Developed for demanding motorsport use, this setup is suited to drifting, circuit racing, time attack, and heavily modified builds where rapid engine response and direct torque transfer are essential.\u003c\/p\u003e\r\n\r\n\u003cp\u003eAt the centre of the kit is a 7.2kg lightweight single mass flywheel, manufactured from 4140 forged steel with an integral ring gear. The high-strength construction provides excellent durability and heat resistance while significantly reducing rotational mass compared with the factory dual-mass setup. The lower inertia allows the engine to rev more quickly, giving sharper throttle response and faster, more precise gear changes.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe clutch assembly features a QT450 steel pressure plate, offering high clamp load and excellent thermal stability during sustained high-temperature and high-load operation. This is paired with a rigid ceramic 6-paddle friction disc, designed without a sprung hub or marcel cushioning to further reduce internal rotational mass and provide more immediate torque transfer.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe ceramic paddle design delivers fast, direct engagement, excellent heat resistance, and strong control under extreme loads. This makes the kit particularly well suited to aggressive launches, clutch kicks, high-RPM driving, and other demanding competition applications where a conventional road clutch may not provide the required level of performance.\u003c\/p\u003e","brand":"Performance Clutches","offers":[{"title":"Default Title","offer_id":57406024024439,"sku":"PC-3194-S4PF","price":824.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/0703\/4172\/files\/PC-3194-S4PF_webp.webp?v=1787588076","url":"https:\/\/mattlewisracing.co.uk\/products\/performance-clutches-bmw-e36-e46-3-series-stage-4-sport-smf-clutch-kit","provider":"Matt Lewis Racing","version":"1.0","type":"link"}
