About this product
DESCRIPTION
The ACT Mod Twin 225 Xtreme Duty Rigid Race Twin Disk Clutch Kit for the 2004-2021 STI is built for high-powered AWD racing where aggressive launches and fast, precise shifts are required. This modular twin disc setup uses dual ceramic friction surfaces paired with a rigid Mono-Drive chrome-moly hub to deliver direct power transfer and very high torque capacity.
A four-stage heat-treated diaphragm maintains a light, consistent pedal feel, while puck-style ceramic friction plates provide excellent heat resistance and durability under extreme conditions. The lightweight, rigid design supports quick shifts, and the kit includes a CNC-machined, dynamically balanced flywheel. Fully rebuildable, it is engineered for long-term race use.
WHY?
This clutch is ideal for drag, road, and rally racing STI builds that demand maximum holding power and immediate engagement. The rigid hub and ceramic twin discs deliver strong torque control and fast response, while ACT’s modular, balanced design ensures reliability during repeated hard launches and high-heat operation.
