ACT HD/Perf Street Sprung Kit BMW 318 | 323 | 325 | 328 | 330 | 525 | 528 | 530 | M3 | Z3 1991-2003 - BM17-HDSS

ACT BM17-HDSS Heavy Duty/Performance Street Sprung Kit

The ACT BM17-HDSS kit is engineered for those who demand reliability and performance from their clutch system. This kit combines ACT's Heavy Duty pressure plate with their popular Performance Street disc, providing a solid foundation for both street and mild race applications.

Pressure Plate Design

The Heavy Duty pressure plate features an exclusive diaphragm design that enhances clamp load while minimizing deflection, leading to improved clutch longevity. Each diaphragm undergoes a rigorous four-stage heat-treating process, ensuring it can withstand the demands of high-performance driving. The precision cover stampings contribute to the overall rigidity and consistency of the pressure plate, making it a reliable choice for enthusiasts.

Performance Street Disc

ACT's Performance Street disc is constructed with premium organic materials that contain a high copper content. This composition not only enhances heat transfer but also ensures the disc maintains its integrity under stress. The steel-backed lining increases burst strength and durability, while reduced marcel allows for quicker shift action, perfectly complementing the Heavy Duty pressure plate.

Specifications

  • Clutch Disc Diameter: 9.4 in (240 mm)
  • Torque Capacity: 465 ft/lbs
  • Input Spline Quantity: 10
  • Input Shaft Diameter: 1.125 in
  • Disc Type: Sprung
  • Weight: 14.9 lbs
  • Pressure Plate Type: Heavy Duty

Installation Notes

Installation of the BM17-HDSS requires the use of an ACT 601011 or 601016 flywheel, which is not included in this kit. The kit comes complete with pressure plate bolts (M8-1.25 x 20mm) and an alignment tool for a straightforward installation process.
