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\u003eFitment\u003c\/h3\u003e\u003cp\u003eLight to moderate pedal effort, aggressive engagement, OE to mild gear rattle; Moderate friction life, extended by ACT's exclusive diaphragm design; Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance; Recommended for high horsepower street or race use; 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1990–1997 Mazda Miata Base\u003c\/li\u003e\n\u003cli\u003e1991 Mazda Miata SE\u003c\/li\u003e\n\u003cli\u003e1993 Mazda Miata LE\u003c\/li\u003e\n\u003cli\u003e1994–1997 Mazda Miata M Edition\u003c\/li\u003e\n\u003cli\u003e1997 Mazda Miata STO\u003c\/li\u003e\n\u003cli\u003e1999 Mazda Miata 10th Anniversary\u003c\/li\u003e\n\u003cli\u003e1999–2005 Mazda Miata Base\u003c\/li\u003e\n\u003cli\u003e2000–2003 Mazda Miata SE\u003c\/li\u003e\n\u003cli\u003e2000–2005 Mazda Miata LS\u003c\/li\u003e\n\u003cli\u003e2003 Mazda Miata Shinsen\u003c\/li\u003e\n\u003cli\u003e2004–2005 Mazda Miata Mazdaspeed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cdl\u003e\n\u003cdt\u003eManufacturer part number\u003c\/dt\u003e\n\u003cdd\u003eZM2-HDG4\u003c\/dd\u003e\n\u003cdt\u003eUPC\u003c\/dt\u003e\n\u003cdd\u003e842385008826\u003c\/dd\u003e\n\u003cdt\u003eShipping weight \u0026amp; size\u003c\/dt\u003e\n\u003cdd\u003e15.70 lb, 14.2 × 14.1 × 6.2 in\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003ch3\u003eDocuments\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/9aea4a88ee91500c37a766fcb5c28a21.PDF\" target=\"_blank\" rel=\"noopener\"\u003eWarranty\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/d856e10aab4787d29e6c192d62ac3288.PDF\" target=\"_blank\" rel=\"noopener\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotices\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer and birth defects or other reproductive harm.
