The ACT Xtreme pressure plate for the 1990 Mazda Miata uses an exclusive diaphragm design and a four-stage heat-treating process to maximize clamp load, reduce deflection and extend clutch life for high-demand applications. Xtreme plates increase clamp load 50–120% and feature precision cover stampings for rigidity. They are recommended with street or race discs and are backed by a one-year warranty.
