ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eLight to moderate pedal effort, aggressive engagement, increased gear rattle\u003c\/li\u003e\n\u003cli\u003eModerate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear\u003c\/li\u003e\n\u003cli\u003eCarefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance\u003c\/li\u003e\n\u003cli\u003eRecommended for race use only\u003c\/li\u003e\n\u003cli\u003e100% clamp load tested and dynamically computer balanced for smooth high RPM reliability\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eClutch Master Cylinder Included: No \u003c\/li\u003e\n\u003cli\u003eGrease Included: Yes \u003c\/li\u003e\n\u003cli\u003eGrade Type: Performance \u003c\/li\u003e\n\u003cli\u003eFlywheel Included: No \u003c\/li\u003e\n\u003cli\u003ePilot Bushing Included: No \u003c\/li\u003e\n\u003cli\u003ePressure Plate Type: Heavy Duty \u003c\/li\u003e\n\u003cli\u003eRelease Bearing Included: Yes \u003c\/li\u003e\n\u003cli\u003eClutch Disc Diameter: 8.4 in\u003c\/li\u003e\n\u003cli\u003eClutch Disc Diameter: 214 mm\u003c\/li\u003e\n\u003cli\u003eDisc Material: Ceramic \u003c\/li\u003e\n\u003cli\u003eInput Spline Quantity: 14 \u003c\/li\u003e\n\u003cli\u003eInput Shaft Diameter: 1 in\u003c\/li\u003e\n\u003cli\u003eAlignment Tool Included: Yes \u003c\/li\u003e\n\u003cli\u003eDisc Type Sprung Solid: Solid \u003c\/li\u003e\n\u003cli\u003ePressure Plate Bolts Included: No \u003c\/li\u003e\n\u003cli\u003eClutch Slave Cylinder Included: No \u003c\/li\u003e\n\u003cli\u003eFlywheel Bolts Included: No \u003c\/li\u003e\n\u003cli\u003ePilot Bearing Included: No \u003c\/li\u003e\n\u003cli\u003eProduct Weight (lbs.): 10.4 \u003c\/li\u003e\n\u003cli\u003eTorque Capacity (ft\/lbs.): 345 \u003c\/li\u003e\n\u003cli\u003eTorque Capacity Over OE: 0.54 \u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReferences\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.vividracing.com\/file\/vr\/148\/2025\/ACT_General_Installation_Instructions.pdf\" target=\"_blank\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003cbr\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2002 Mini Cooper S\u003c\/li\u003e\n\u003cli\u003e2003 Mini Cooper S\u003c\/li\u003e\n\u003cli\u003e2004 Mini Cooper S\u003c\/li\u003e\n\u003cli\u003e2005 Mini Cooper S\u003c\/li\u003e\n\u003cli\u003e2006 Mini Cooper S\u003c\/li\u003e\n\u003cli\u003e2007 Mini Cooper S\u003c\/li\u003e\n\u003cli\u003e2008 Mini Cooper S\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/ul\u003e","brand":"C-Dub Tech","offers":[{"title":"Default Title","offer_id":46064758685849,"sku":"ACT BM2-HDR4","price":621.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0062\/2306\/9284\/files\/BM2-HDR4.webp?v=1767599540","url":"https:\/\/cdubtech.com\/products\/advanced-clutch-hd-race-rigid-4-pad-kit-bm2-hdr4","provider":"C-Dub Tech","version":"1.0","type":"link"}
