Spec 06-10 Subaru WRX/07-10 Legacy GT (including Spec B) Stage 4 Clutch Kit - Unsprung Race Use ONLY

Built with a solid 6-puck sprung hub, this SPEC Stage 4 clutch kit is designed for the demands of racing applications. The unsprung design means there are no dampening springs in the clutch disc itself, which helps handle the extreme torque and shock loads common in competitive driving. This setup is specifically tuned for vehicles that see regular track time or intense performance use, offering a direct and robust engagement that drivers can rely on when pushing their Subaru Forester to its limits.

This Stage 4 kit includes a high-clamp load pressure plate, a 6-puck rigid (unsprung) disc, and a pilot bearing. The rigid disc is crucial for transferring power quickly and efficiently without the flex that can occur with sprung designs under high stress. While this setup offers a significant increase in holding capacity compared to stock, it's important to note that it is intended for race use only. This means you can expect a more abrupt engagement and potentially increased drivetrain noise, which are trade-offs for the enhanced performance and durability under extreme conditions. The high-clamp load pressure plate ensures that the clutch can handle the increased torque without slipping, making it a solid choice for dedicated performance builds.

When installing this clutch kit, be prepared for a firmer pedal feel and a more direct engagement. It's recommended to have all necessary supporting components ready, as this is a performance-oriented upgrade. This kit is a serious consideration for anyone looking to maximize their Subaru's drivetrain performance for track days or competitive events, offering a well-built solution for high-torque applications.
