Description:

The T1R-S05 Mod-Twin 225 HD Sprung Race Kit is designed to facilitate aggressive launches and smoother shifting in high-powered AWD vehicles. This kit combines twice the ceramic friction surfaces with an ultra-durable Mono-Drive sprung hub assembly in a modular design. Each diaphragm spring undergoes an exclusive four-stage heat-treating process, ensuring a consistent light pedal feel. Puck-style friction plates with high-quality ceramic friction materials deliver a 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. 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.

Description Highlights:

• Feel: Predictable aggressive engagement, light pedal effort, quick shifting, possible start-off judder 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-term performance and survival under demanding conditions
• Quality: Delivers maximum performance and high heat tolerance through robust design, strategic features, choice materials, and close tolerances
• Recommended Use: Drag, Road, or Rally Racing
• ACT Difference: Applying tactical engineering to the MOD-TWIN, ACT presents unique solutions to common trade-offs 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

Vehicle Fitment:

• 2004-2021 Subaru Impreza WRX STI, various models
