Xclutch 9in Twin Sprung Ceramic Clutch Kit – 2004-2021 Subaru STI

Twin Disc Power Handling With More Manageable Engagement
The XClutch Twin Sprung Ceramic clutch kit combines the maximum torque capacity and heat resistance of ceramic friction material with the sprung hub design that gives the best engagement character for a twin ceramic disc setup. This is designed for high-performance motorsport applications — circuit, time attack, gymkhana — where very high torque capacity is required and the driver wants some compliance in the engagement to protect the transmission.

Why Sprung Ceramic for Twin Disc
The sprung ceramic disc uses a spring-damped hub to reduce shock loading on the transmission at engagement, which is important in motorsport applications where gear changes are frequent and the transmission is under sustained stress. Ceramic material provides excellent heat capacity for sustained track use, and the twin disc configuration handles very high torque levels that would overwhelm any single disc design.

Why Choose XClutch
XClutch has been engineering performance clutch systems for over 30 years, with one of the most advanced clutch testing and R&D facilities in the world. Every kit is developed with in-house vehicle testing, and their full product range covers everything from street performance upgrades to dedicated race applications. For Subaru WRX, STI, and the GR Corolla/BRZ platform, XClutch’s depth of application-specific development is difficult to match at this price point.

The RallySport Take

The Twin Sprung Ceramic is for serious performance builds — cars making big power that spend meaningful time at the track. The engagement requires practice and commitment; this is not a clutch for casual use. The sprung hub makes the twin ceramic more manageable than a twin solid ceramic, but it still demands a deliberate, decisive clutch release. If the car is a track weapon that occasionally drives to the event, this is a strong choice.
