Introduction

2001-2006 BMW M3 E46 HD/RaceRigid 4-Pad Clutch Kit by ACT

BM9-HDG4 kit features ACT’s most popular Heavy Duty pressure plate and a 4 padrigid race disc.

ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency.

ACT’s 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.

ACT clutches deliver the maximum holding power through applying a series of sound engineering advancements to new not rebuilt components that maximize load and reduce flex. The result is maximum torque capacity, long life and clean, fast shifting.
