ACT Mod Twin 225 Heavy Duty Rigid Street Twin Disk Clutch Kit 2004-2021 STI

DESCRIPTION

The ACT Mod Twin 225 Heavy Duty Rigid Street Twin Disk Clutch Kit for the 2004-2021 STI is built for high-powered AWD street and street/strip cars that want smooth, responsive shifts with strong torque capacity. This modular twin disc system pairs dual organic friction surfaces with a rigid Mono-Drive chrome-moly hub for direct power transfer and consistent engagement.

A four-stage heat-treated diaphragm delivers a light, progressive pedal feel, while steel-backed organic friction plates provide stable friction, good heat capacity, and long service life. The lightweight, rigid design supports quicker shifts, and the kit includes a CNC-machined, dynamically balanced flywheel. Fully rebuildable, it is engineered for long-term reliability.

WHY?

This clutch is ideal for STI owners who want a street-friendly twin disc setup with a more direct, responsive feel. The rigid hub improves shift response, while the organic discs maintain smooth engagement and durability under high power conditions.

FEATURES:

  • Soft and progressive engagement with light pedal effort

  • Mild to moderate transmission gear noise

  • Dual organic friction surfaces for high torque capacity

  • Rigid Mono-Drive chrome-moly hub for direct power transfer
