The ACT ZM15-HDSD kit features ACT's most popular Heavy Duty pressure plate paired with a performance street rigid-hub disc for the 2019-2025 Mazda MX-5 Miata. The rigid-hub disc uses premium organic friction materials with high copper content for better heat transfer and a steel-backed lining for greater burst strength and durability. Its chrome-moly hub is heat-treated for strength, and rivet design and materials are selected for maximum durability. As the minimum-weight street disc in ACT's lineup, it delivers the fastest shifts of any street-manageable disc while providing race-proven performance.
