ACT Extreme Race Sprung 6 Pad Clutch Kit 2004-2021 STI

DESCRIPTION

The ACT Extreme Race Sprung 6 Pad Clutch Kit is built for 2004–2021 Subaru WRX STI models that need extreme torque capacity with manageable drivability for high horsepower street or race applications. This kit pairs a sprung 6-pad ceramic race disc with ACT’s Xtreme diaphragm pressure plate, delivering a robust clamp load and spring-centered damping to control torsional vibrations. Rated to handle up to 766 ft-lbs of torque, the assembly uses precision cover stampings and a four-stage heat-treat process for durability under repeated high-RPM use. The included Monoloc one-piece chrome-moly retaining ring provides uniform bearing loading and alignment for long-term reliability.

WHY?

Choose this kit if your STI is making serious power and you need a clutch that holds big torque while remaining usable on the street and confident on the track. The sprung hub helps absorb driveline shock and reduces drivability issues compared with rigid race discs, while the Xtreme pressure plate and heat-treated components deliver consistent clamp load and improved longevity under extreme conditions. This kit gives racers and high-power street drivers the strength and repeatability required for aggressive driving and frequent track sessions.
