2006-2026 Subaru WRX

The ACT Extreme Race Rigid 4-Pad Clutch Kit is engineered for drivers who demand maximum performance from their clutch system under high-stress and racing conditions. Featuring ACT’s Xtreme pressure plate and a rigid 4-pad ceramic disc, this kit is ideal for aggressive street builds and dedicated motorsport applications.

ACT’s proprietary four-stage heat-treated diaphragm delivers increased clamp load with reduced deflection, resulting in stronger grip, improved torque capacity, and resistance to heat-related fade. The rigid ceramic disc provides fast, positive engagement and improved throttle response, while precision balancing ensures reliable operation at high RPM.

Technical & Fitment Notes

This clutch kit uses a rigid ceramic friction disc, offering excellent torque transfer and heat resistance. Due to its aggressive design, increased drivetrain noise and harsher engagement may be present compared to organic or sprung-hub clutches. Best suited for drivers prioritizing performance over daily-driving comfort.
