ACT's most popular Heavy Duty pressure plate paired with their most popular street disc — a combination built around drivability rather than chasing the highest possible clamp number.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eHeavy Duty pressure plates use ACT's exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life, with every diaphragm going through a four-stage heat-treating process. Precision cover stampings give the assembly rigidity and consistency. Clamp load comes in 20 to 50 percent over OEM.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe Performance street disc is premium organic with high copper content for better heat transfer, and steel-backed lining for greater burst strength and durability. Reduced marcel gives faster shift action. The result is light to moderate pedal feel with smooth engagement and quiet operation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eMonoloc is included.\u003c\/strong\u003e It's a one-piece replacement for the standard two-piece wedge collar and wire ring used in pull-type clutches, providing uniform loading on the bearing and pressure plate so alignment stays correct regardless of driver influence or how the car's been modified.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eRated to \u003cstrong\u003e522 lb-ft.\u003c\/strong\u003e 24-spline on a 1.000\" input shaft. Every assembly is 100 percent clamp load tested and computer spin balanced to within .25 oz-in, versus roughly .50 for a stock production clutch.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 04-21 Subaru WRX STI, 07-09 Legacy GT Spec B. Legacy GT Spec B applications need the STI flywheel to run this clutch.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003ePedal effort increases 15 to 40 percent over stock. ACT is direct about why: clutches developed with less pedal effort tend to give up longevity, torque capacity, or engagement quality.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eBreak-in:\u003c\/strong\u003e 300-500 miles of mild stop-and-go driving before spirited use.
