ACT 06-25 Subaru WRX XT/Race Sprung 4 Pad Clutch Kit

ACT Xtreme Race Sprung 4-Pad Clutch Kit for Subaru WRX and EJ-Series Models

The ACT Xtreme Race Sprung 4-Pad Clutch Kit for the 2006-2026 Subaru WRX and EJ-series models is the sprung-center version of the 4-pad race kit paired with the Xtreme pressure plate. The spring-center construction damps torsional vibrations while the 4-pad ceramic disc handles the heat of hard driving. Well-suited for smaller disc sizes where the 4-pad is the appropriate configuration.

DETAILS

• Pressure plate: ACT Xtreme, maximum clamp load
• Clutch disc: 4-pad spring-centered race
• Disc material: ceramic friction
• Hub: chrome-moly, heat-treated, spring-center
• Spring retainers: wraparound windows, thicker stampings
• Use case: performance street/track, smaller disc applications
• Engagement: harsher than street disc, more compliant than rigid 4-pad

The 4-pad spring-centered disc uses the same ACT spring retainer design as the 6-pad sprung, wraparound spring windows and thicker retainer stampings for durability. The spring center damps vibrations that rigid discs transmit to the driveline, making repeated engagement less punishing on the transmission input shaft and shift forks.

The 4-pad configuration is well-suited for smaller disc diameters. On the EJ-series WRX platform, the 4-pad sprung is the choice for builds where the spring-center compliance is desired alongside the ceramic pad heat performance, in a lighter package than the 6-pad.

Why Choose ACT

Advanced Clutch Technology has been manufacturing performance clutch systems in the United States since 1993. Every ACT pressure plate uses a proprietary diaphragm design that increases clamp load and reduces deflection compared to OEM units, and every diaphragm goes through a four-stage heat-treating process before it leaves the factory. The result is a clutch system that holds more power than the stock unit, engages more precisely, and lasts longer under the kind of driving that wears factory clutches out quickly. ACT designs each application from scratch rather than modifying OEM tooling, which means the fitment is precise and the performance is intentional. Whether the build is a street-driven daily driver or a dedicated track car, ACT offers a kit at the correct specification for the use.

The RallySport Take

The ACT Xtreme 4-pad Sprung race kit is the correct choice for builds that see both track and street use. The ceramic pads provide the heat capacity you need for sustained hard driving, and the spring-center hub construction damps the torsional shocks that rigid discs transmit directly to the drivetrain. ACT’s wraparound spring window design and thicker retainer stampings make the spring center more durable under repeated hard engagement than standard designs. The result is a clutch that performs like a race disc at the track and does not punish you for driving home afterward. Fits Subaru applications 2005,2007-2025.
