Introduction

2001-2006 BMW M3 E46 HD/Perf StreetRigid Clutch Kit by ACT

BM9-HDSD kit features ACT’s most popular Heavy Duty pressure plate and ACT’s performance street rigid-hub 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.

The ACT performance street rigid-hub discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. The chrome-moly hub is heat-treated for strength and durability. Rivet design and materials are carefully selected for maximum strength. These discs are the minimum weight street disc for faster shifts. ACT’s street rigid-hub discs provide race-proven performance with street manageability.

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.
