ACT Mod-Twin 225 XT Sprung Street Clutch Kit 

With a torque capacity of 875 ft-lbs, the ACT Mod-Twin 225 XT Sprung Street Clutch Kit is ideal for those of you with Subaru STI models that are making some steam. This clutch kit features twice the organic friction surfaces with an ultra-durable spring-center mono-drive hub assembly in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat-treating process that provides a consistent light-pedal feel. The puck-style friction plates with high-quality organic friction materials deliver a high friction coefficient, superior heat capacity, and longer clutch life. The friction plates uniformly transfer torque to a Mono-Drive sprung hub assembly which extends input shaft life and reduces driveline shock from torsional vibration.
