About this product
DESCRIPTION
The ACT Mod Twin 225 Xtreme Duty Sprung Street Twin Disk Clutch Kit for the 2004-2021 STI is engineered for high-powered AWD street cars that demand very high torque capacity without sacrificing drivability. This modular twin disc system combines dual organic friction surfaces with an ultra-durable sprung Mono-Drive hub to deliver smooth engagement, controlled pedal feel, and long service life. An exclusive four-stage heat-treated diaphragm provides consistent, light pedal effort, while steel-backed friction plates offer stable friction and strong heat capacity.
Torque is transferred evenly through the sprung Mono-Drive hub to reduce driveline shock and extend input shaft life. The kit includes a CNC-machined, dynamically balanced flywheel and a complete clutch assembly designed for durability, rebuild ability, and long-term performance in demanding street and street/strip applications.
WHY?
This clutch is ideal for STI owners running high power who want twin disc performance with street-friendly manners. The dual organic discs provide strong holding power with progressive engagement, while the sprung hub helps protect the drivetrain during daily driving and hard launches. Its fully modular, rebuildable design makes it a long-term solution for serious builds that still see regular street use.
