ACT Extreme Race Rigid 4 Pad Clutch Kit 2004-2021 STI

DESCRIPTION

The ACT Extreme Race Rigid 4 Pad Clutch Kit is designed for 2004–2021 Subaru WRX STI models that demand race-ready durability and high torque capacity. This kit combines a rigid 4-pad ceramic race disc with ACT’s Xtreme diaphragm pressure plate, providing strong torque transfer for track-only applications. Rated to handle up to 766 ft-lbs of torque, the lightweight, heat-treated components and chrome-moly hub deliver long-term durability while allowing quicker shifts. The disc is well-suited for smaller clutch sizes, and the included Monoloc one-piece retaining ring ensures proper alignment and consistent performance under extreme conditions.

The rigid 4-pad disc and Xtreme pressure plate provide durability and consistent clamp load, while the Monoloc system maintains proper bearing alignment. If you are building a track-focused vehicle, this clutch delivers reliable, long-lasting performance for high-demand racing conditions.
