ACT Heavy Duty Race Rigid 6 Pad Clutch Kit 2004-2021 STI

DESCRIPTION

The ACT Heavy Duty Race Rigid 6 Pad Clutch Kit is built for 2004–2021 Subaru WRX STI models that demand track-ready durability and torque capacity. This kit pairs a rigid 6-pad ceramic race disc with ACT’s Xtreme diaphragm pressure plate to deliver direct power transfer, reduced rotating mass, and reliable performance in race-only applications. Rated to handle up to 668 ft-lbs of torque, the assembly uses heat-treated components and precision stampings for consistent clamp load and long service life. The chrome-moly hub and rigid disc design allow the clutch to absorb more heat while maintaining stability under extreme conditions, making it ideal for larger clutch setups and high RPM track use.

WHY?

This kit is designed for drivers building a purpose-built race car who need a clutch that delivers maximum strength and repeatable engagement. ACT’s Xtreme pressure plate and Monoloc bearing system provide consistent clamp load and proper alignment, ensuring reliable performance lap after lap. If you’re pushing your STI to its limits, this clutch kit provides the durability and confidence required to perform at the track.
