Description:

The T1S-S05 Mod-Twin 225 HD Sprung Street Kit is specifically designed for high-powered AWD street cars. It offers uncompromised pedal feel, durability, and engagement quality with a very high torque capacity by combining twice the organic friction surfaces with an ultra-durable spring center Mono-Drive hub in a modular design.

Each diaphragm spring undergoes an exclusive four-stage heat-treating process, providing a consistent light pedal feel. The steel-backed friction plates, featuring high-quality organic friction materials, deliver a stable friction coefficient, good heat capacity, and long clutch life. These friction plates uniformly transfer torque to the Mono-Drive sprung hub assembly, extending input shaft life and reducing driveline shock from torsional vibration.

The 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:

• Feel: Soft progressive engagement, light pedal effort, smooth shifting with OE to mild transmission gear noise.
• Life: Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure long-life performance under demanding conditions.
• Quality: Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances.
• Recommended Use: Street or Street/Strip.
• ACT Difference: Utilizes tactical engineering to address common tradeoffs found in twin-disc clutches, resulting in an ultra-durable, customer-serviceable, long-lasting clutch with very high torque capacity. All clutches are 100% clamp load tested, balanced, and SFI certified.

Vehicle Fitment:

• Application: Engine
  • Various Subaru Impreza WRX STI models from 2004 to 2021 with 2.5 H4 GAS FI 2458cc engines, DOHC configuration, and Turbocharged.
