ACT's T2S-S05 kit features a Mod-Twin 225 clutch discs paired with their ever popular Xtreme pressure plate. What does this mean for you? Well, that means that you will have soft progressive engagement with light pedal effort and the ability to handle up to 875ft/lbs of torque on your STI. This clutch kit is best suited for street or street/strip.

It unites uncompromised pedal feel, durability, engagement quality with very high torque capacity by combining twice the organic friction surfaces with an ultra-durable spring center Mono-Drive hub in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process providing a consistent light pedal feel. Steel-backed Friction Plates with high quality organic friction materials deliver stable friction coefficient, good heat capacity and long clutch life. These Friction Plates uniformly transfer torque to the 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, and alignment tool.. Mod-Twin clutches are fully rebuildable and most components can be ordered separately.

  • Torque Capacity (ft/lbs.) - 875
  • Feel - Soft progressive engagement, light pedal effort, smooth shifting with OE to mild transmission gear noise
  • Recommended Use - Recommended for Street or Street/Strip
  • ACT Difference - 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
