ACT Mod-Twin 225 XT Sprung Street Clutch Kit for 2004-2021 Subaru WRX STI (875 ft/lbs) T2S-S05

Fits select 2004-2021 Subaru Impreza WRX STI and WRX STI models.

The ACT T2S-S05 Mod-Twin 225 XT Sprung Street Kit is engineered for high-powered, All-Wheel Drive street applications that require massive torque capacity without sacrificing drivability. By utilizing a modular design with double the organic friction surface area, this kit provides a stable friction coefficient and excellent heat capacity for long-term durability. The exclusive four-stage heat-treating process applied to the diaphragm spring ensures a consistent, light pedal feel, while the patented Monoloc Collar ensures the release bearing remains securely in place during high-RPM operation.

The heart of this system is the ultra-durable Mono-Drive hub. This sprung assembly is designed to reduce driveline shock and dampen torsional vibrations, protecting your input shaft and transmission. Fully rebuildable, the Mod-Twin series allows for individual component replacement, making it a sustainable long-term solution for modified STI builds.
