Product Description

Advanced Clutch Technology (ACT) ZM8-HDR4 - ACT HD/Race Rigid 4 Pad Kit Mazda RX-8 Touring 1.3R; 2008-2009.

ZM8-HDR4 kit features ACT's most popular Heavy Duty pressure plate. 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.


  • Light to moderate pedal effort, aggressive engagement, increased gear rattle

About Advanced Clutch Technology (ACT)

History and information about Advanced Clutch Technology (ACT) and their products.

You are on this page because you are in the market for a new clutch, flywheel or some other performance part and the team at LMPERFORMANCE knows this can be a daunting task because there are many nuances that are peculiar and necessary for the selection of a top notch clutch or other performance item. Consideration must be given to engine torque, maximum RPM, available grip for street tires, DOT-T, drag slick and others, the type of driving whether it is on the street, for sport, for track events or for racing, and your driving style and by that we mean what you actually do and not what you should do or want to do, and lets not forget FWD/RWD/AWD.

For both performance and safety you will want to choose the best from a company that has proven itself in the aftermarket performance field and whose longevity gives it the expertise necessary to offer you a sans pareil product that can be installed with confidence in its ability to do what is designed to do.
