The ACT Mod-Twin 225 Max Extreme XX Sprung Race Clutch Kit is a high-performance clutch designed for Subaru Impreza WRX STI models from 2004 to 2020. This kit features a puck-style ceramic friction surface with twice the contact area, providing exceptional grip and aggressive launch capabilities. The inclusion of an ultra-durable Mono-Drive sprung hub assembly ensures smooth engagement and longevity under demanding conditions. Constructed with high-quality ceramic friction materials and a four-stage heat treating process, the clutch delivers consistent pedal feel with moderate effort, making it suitable for high-powered AWD applications. Its modular design allows for easy installation and reliable performance during intense driving scenarios, whether on the street or track.

This clutch kit is specifically engineered for 2004-2020 Subaru Impreza WRX STI models, compatible with various engine configurations within this range. It serves as a direct replacement for stock units, offering increased holding capacity and improved response for aggressive driving and racing. The kit is ideal for enthusiasts seeking a reliable upgrade for high horsepower builds, drag racing, or spirited street driving. Installation involves standard bolt-on procedures, and the kit typically includes the clutch disc, pressure plate, and release bearing. Designed to withstand high torque loads, the ACT Mod-Twin 225 Max Extreme XX is perfect for those demanding maximum performance from their AWD Subaru.

Overview

T3R-S05 Mod-Twin 225 XX Sprung Race Kit performs aggressive launches and smoother shifting in high powered AWD by combining twice the ceramic friction surfaces with an ultra-durable Mono-Drive sprung hub assembly in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process providing a consistent pedal feel requiring moderate effort. Puck-style Friction Plates with high quality ceramic friction materials deliver high friction coefficient, superior heat capacity, and long clutch life. These Friction Plates uniformly transfer torque to a Mono-Drive sprung hub assembly which extends input shaft life and reduces driveline shock from torsional vibration. This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, sprung Mono-Drive hub assembly, floater, patented Monoloc Collar, release bearing, alignment tool and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable and most components can be ordered separately.

Features:

  • Predictable aggressive engagement, increased pedal effort, smooth shifting, possible start-off judder with OE to mild transmission gear noise
  • Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure this long-life twin performs and survives under the most demanding conditions
  • Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances
  • Drag, Road or Rally Racing
  • Applying tactical engineering to the MOD-TWIN, ACT presents unique solutions to common tradeoffs found on twin disc clutches, resulting in an ultra-durable, customer serviceable, long-lasting clutch with very high torque capacity. All are 100% clamp load tested, balanced and SFI certified
