Upgrade your stock clutch with the ACT HD/Performance clutch which is made for both heavy duty and street racing applications. BM8-HDR4 fits BMW E90 3-series, E60 5-Series, and Z4 35i.
Advanced Clutch Technology HD/Race Rigid Clutch Kit features ACT's most popular heavy duty pressure plate. ACT uses exclusive diaphragm design to not only increase clamp load, but also to reduce defection and maximize clutch life. Each of the clutch diaphragms go through a four-stage heat treating process which gives unparalleled performance. The pressure plates in this kit have precision cover stampings which provide rigidity and consistency. ACT's 4-pad, spring-centered race disc is designed to properly damp torsional vibrations and resist failure under harsh driving conditions. The retainers used in this clutch kit utilize wraparound spring windows with thicker retainer stampings which not only provide spring support but reduces the stress concentrations while increasing strength and reliability. Because a 6-pad race disc is used, engagement is harsher but shifting is faster.
