The ACT Heavy Duty Pressure Plate for the 2007 BMW 335i uses an exclusive diaphragm design to increase clamp load, reduce deflection and extend clutch life. ACT applies a four-stage heat-treating process to the diaphragm and precision cover stampings for rigidity. Clamp load is increased by 20–50%, and the Heavy Duty plate is recommended for use with a street or race disc and includes a one-year warranty.
