ACT Xtreme Performance Street Sprung Clutch 2004-2021 STI

DESCRIPTION

The ACT Xtreme Performance Street Sprung Clutch for the 2004-2021 STI is designed for high-output builds that still see street use. It features an ACT Xtreme pressure plate with an exclusive diaphragm design that increases clamp load while reducing deflection and extending clutch life. Precision-stamped covers and a multi-stage heat-treated diaphragm ensure consistent performance under aggressive driving.

This kit includes ACT’s Performance Street sprung disc with premium organic friction material and higher copper content for improved heat transfer and durability. A reduced marcel allows quicker shift response with smooth engagement, while ACT’s patented Monoloc one-piece release mechanism improves alignment, bearing loading, and long-term reliability in pull-type applications.

WHY?

This clutch is a strong choice for STI owners who need higher torque capacity and confidence during hard shifts without giving up drivability. The increased clamp load provides secure holding power, while the organic sprung disc and refined release mechanism keep engagement controlled and predictable for both street and track use.
