Introduction

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

BM9-HDSS kit features ACT’s most popular Heavy Duty pressure plate and most popular street 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 Performance Street discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. These discs have reduced marcel for faster shift action to complement ACT pressure plates, with increased strength and reliability.

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.
