ACT T2S-S05 Mod-Twin 225 XT Sprung Street Clutch Kit for Subaru WRX STI

T2S-S05 Mod-Twin 225 XT Sprung Street Kit is designed for high powered AWD street cars. 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, alignment tool and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable and most components can be ordered separately. Mod-Twin 225 XT Sprung Street Soft progressive engagement, light pedal effort, smooth shifting 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; Street or Street/Strip; 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

• "Excellence in Performance", backed by the best one-year warranty in the industry!

The ACT T2S-S05 Mod-Twin 225 XT Sprung Street Clutch Kit is engineered for high-powered AWD street cars, including the 2015-2018 Subaru WRX STI. This modular twin-disc clutch system combines smooth, progressive engagement and light pedal effort with the strength required for demanding street and street/strip applications. Its dual organic friction surfaces and sprung Mono-Drive hub provide high torque capacity while helping reduce driveline shock and extend input shaft life.

Each ACT diaphragm spring undergoes a proprietary four-stage heat-treating process to maintain consistent clamping force and comfortable pedal operation. Steel-backed friction plates with premium organic friction material deliver a stable friction coefficient, dependable heat management, and long service life. The system also uses a forged aluminum cover, hardened wear points, a dynamically balanced flywheel, and an ACT Monoloc Collar for precise operation and improved durability. The clutch is fully rebuildable, allowing individual components to be serviced or replaced as needed.

Designed for approximately 875 lb-ft of torque capacity, the T2S-S05 provides a practical balance of performance, drivability, and durability. Every unit is clamp-load tested, balanced, and SFI certified. The kit includes the primary clutch hardware and installation components needed for a complete conversion, including a release bearing, alignment tool, and pilot bearing when required. ACT backs this performance clutch with a one-year warranty.

Fitment: Designed for 2015-2018 Subaru WRX STI applications. Verify transmission, engine, and vehicle configuration before installation.
