The ACT Heavy Duty pressure plate for Mazda Mazdaspeed3 2.3T (2007–2013) uses a proprietary diaphragm design to increase clamp load, reduce deflection and extend clutch life. ACT applies a four-stage heat-treat process to its diaphragms and precision cover stampings for rigidity and consistency. These heavy duty plates raise clamp load by roughly 20–50% and are recommended for use with street or race discs.
