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\u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"231\" style=\"border-collapse: collapse; width: 501px;\"\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"64\" style=\"width: 162px;\"\u003e \u003ccol width=\"167\" style=\"width: 338px;\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr height=\"62\" style=\"height: 46.8pt;\"\u003e\n\u003ctd height=\"62\" class=\"xl65\" width=\"64\" style=\"height: 46.8pt; width: 48pt;\"\u003e\u003cstrong\u003eFeel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"xl66\" width=\"167\" style=\"border-left: none; width: 125pt;\" data-th=\"Feel\"\u003eLight to moderate pedal effort, aggressive engagement, OE to mild gear rattle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"62\" style=\"height: 46.8pt;\"\u003e\n\u003ctd height=\"62\" class=\"xl65\" width=\"64\" style=\"height: 46.8pt; border-top: none; width: 48pt;\"\u003e\u003cstrong\u003eLife\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"xl66\" width=\"167\" style=\"border-top: none; border-left: none; width: 125pt;\" data-th=\"Life\"\u003eModerate friction life, extended by ACT's exclusive diaphragm design\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"125\" style=\"height: 93.6pt;\"\u003e\n\u003ctd height=\"125\" class=\"xl65\" width=\"64\" style=\"height: 93.6pt; border-top: none; width: 48pt;\"\u003e\u003cstrong\u003eQuality\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"xl66\" width=\"167\" style=\"border-top: none; border-left: none; width: 125pt;\" data-th=\"Quality\"\u003eCarefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"62\" style=\"height: 46.8pt;\"\u003e\n\u003ctd height=\"62\" class=\"xl65\" width=\"64\" style=\"height: 46.8pt; border-top: none; width: 48pt;\"\u003e\u003cstrong\u003eRecommended Use\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"xl66\" width=\"167\" style=\"border-top: none; border-left: none; width: 125pt;\" data-th=\"Recommended Use\"\u003eRecommended for high horsepower street or race use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr height=\"83\" style=\"height: 62.4pt;\"\u003e\n\u003ctd height=\"83\" class=\"xl65\" width=\"64\" style=\"height: 62.4pt; border-top: none; width: 48pt;\"\u003e\u003cstrong\u003eACT Difference\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"xl66\" width=\"167\" style=\"border-top: none; border-left: none; width: 125pt;\" data-th=\"ACT Difference\"\u003e100% clamp load tested and dynamically computer balanced for smooth high RPM reliability\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003eThis Part Fits:\u003c\/p\u003e\n\u003ctable border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth align=\"left\" width=\"100\"\u003eYear\u003c\/th\u003e\n\u003cth align=\"left\" width=\"125\"\u003eMake\u003c\/th\u003e\n\u003cth align=\"left\" width=\"150\"\u003eModel\u003c\/th\u003e\n\u003cth align=\"left\" width=\"80\"\u003eSubmodel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1990-1993\u003c\/td\u003e\n\u003ctd\u003eMazda\u003c\/td\u003e\n\u003ctd\u003eMiata\u003c\/td\u003e\n\u003ctd\u003eBase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1993\u003c\/td\u003e\n\u003ctd\u003eMazda\u003c\/td\u003e\n\u003ctd\u003eMiata\u003c\/td\u003e\n\u003ctd\u003eLE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1991\u003c\/td\u003e\n\u003ctd\u003eMazda\u003c\/td\u003e\n\u003ctd\u003eMiata\u003c\/td\u003e\n\u003ctd\u003eSE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003ca target=\"_blank\" href=\"https:\/\/advancedclutch.com\/media\/pdfs\/ACT_General_Installation_Instructions.pdf\" rel=\"noopener\" aria-describedby=\"a11y-new-window-external-message\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/corvetterealm.com\/collections\/vendors?q=ACT\"\u003eShop all of our ACT products\u003c\/a\u003e\u003c\/p\u003e","brand":"ACT","offers":[{"title":"Default Title","offer_id":44393876127881,"sku":"ACTZM1-HDG4","price":639.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/5636\/0585\/files\/be57c53cdd65d7cd3748a78a7ac06deaL.jpg?v=1752362813","url":"https:\/\/corvetterealm.com\/products\/act-miata-clutch-zm1-hdg4","provider":"Corvette Realm","version":"1.0","type":"link"}
