The ACT HD/Modified Street clutch kit for 2005 Mazda 3 pairs a heavy-duty pressure plate with a modified street disc to increase clamp load and improve clutch life. ACT's diaphragm pressure plate is heat-treated in four stages and uses precision cover stampings for rigidity. The modified street disc features premium organic friction with high copper content and steel-backed lining, reduced marcel for faster shifts, and stronger torsional springs for smoother, reliable engagement.
