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 spring-centered race disc features a spring-center to properly damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. ACT's 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLight to moderate pedal effort, aggressive engagement, OE to mild gear rattle\u003c\/li\u003e\n\u003cli\u003eModerate friction life, extended by ACT's exclusive diaphragm design\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 high horsepower street or race use\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\n\u003cp\u003e\u003cstrong\u003ePlease Note:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMust use ACT Flywheel (Included in kit)\u003c\/li\u003e\n\u003cli\u003eRecommended for race use only\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2013-2016 Scion FR-S\u003c\/li\u003e\n\u003cli\u003e*Conversion kit - Includes ACT Prolite flywheel.\u003c\/li\u003e\n\u003cli\u003e2013-2021 Subaru BRZ\u003c\/li\u003e\n\u003cli\u003e*Conversion kit - Includes ACT Prolite flywheel.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Instructions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eClick Here!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's in the box?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 - 4224218-1 - 4 Pad Sprung Race Disc\u003c\/li\u003e\n\u003cli\u003e1 - 600700 - XACT Flywheel Prolite\u003c\/li\u003e\n\u003cli\u003e1 - AT90 - Alignment Tool\u003c\/li\u003e\n\u003cli\u003e1 - PB1004 - Pilot Bearing\u003c\/li\u003e\n\u003cli\u003e1 - RB004 - Release Bearing\u003c\/li\u003e\n\u003cli\u003e1 - SB017 - P\/PL Heavy Duty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDescription: HD\/Race Sprung 4 Pad\u003c\/li\u003e\n\u003cli\u003eTorque Capacity (ft\/lbs.): 345\u003c\/li\u003e\n\u003cli\u003eTorque Capacity Over OE: 1.17\u003c\/li\u003e\n\u003cli\u003eFlywheel Tooth Count: 124\u003c\/li\u003e\n\u003cli\u003eDisc Type: Race Disc\u003c\/li\u003e\n\u003cli\u003eSpline Count: 24\u003c\/li\u003e\n\u003cli\u003eSpline Size (in.): 1\u003c\/li\u003e\n\u003cli\u003eDisc Diameter (in.): 8.8\u003c\/li\u003e\n\u003cli\u003eDisc Diameter (mm.): 224\u003c\/li\u003e\n\u003cli\u003ePressure Plate Type: Heavy Duty\u003c\/li\u003e\n\u003cli\u003eProduct Weight (lbs.): 24.8\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003eFrequently asked questions\u003ch3\u003eWill this ACT Clutch Kits \u0026amp; Flywheels part fit my vehicle?\u003c\/h3\u003e\u003cp\u003eIt fits the vehicles listed in the title and product details.
