ACT XT-M/Race Rigid 6 Pad Kit Subaru Impreza | Legacy | STI | WRX 2000-2021 - SB10-XTR6

ACT SB10-XTR6 Clutch Kit

The ACT SB10-XTR6 is engineered for the performance-driven driver seeking reliability and responsiveness in high-stress environments. This kit features the Xtreme pressure plate, which utilizes an exclusive diaphragm design that enhances clamp load, minimizes deflection, and maximizes clutch longevity. Each diaphragm undergoes a four-stage heat-treating process, ensuring exceptional performance under demanding conditions.

Construction and Design

The precision cover stampings of the ACT pressure plate provide the necessary rigidity and consistency for optimal operation. Complementing this is the 6-pad rigid race disc, crafted from high-quality ceramic friction materials. The heat-treated chrome-moly hub enhances strength and durability, allowing for quicker shifts and consistent engagement. While the engagement may be harsher, the design facilitates faster shifting, making it ideal for competitive scenarios.

Performance Features

  • Moderate to heavy pedal effort with aggressive engagement for enhanced driver confidence during hard shifts.
  • Engineered for moderate friction life, extended by ACT's diaphragm design, which also improves the release mechanism's lifespan.
  • Dynamic computer balancing ensures smooth operation at high RPMs, with 100% clamp load testing for reliability.
  • Includes ACT's patented Monoloc for improved alignment and performance.

  • Clutch Disc Diameter: 9.4 in (240 mm)
  • Torque Capacity: 766 ft/lbs, surpassing OE specifications by 1.15 times
  • Input Spline Quantity: 24
