Fitment Information: This clutch kit is designed for 2004 - 2021 Subaru STI models. Features: The ACT T2R - S05 kit pairs a Mod - Twin 225 sprung clutch disc with a popular Xtreme pressure plate. You'll enjoy predictable and aggressive engagement with light pedal effort and smooth shifting. This twin clutch kit can handle up to 1120 ft/lbs of torque, making it ideal for drag, road, and rally racing. The Mod - Twin 225 XT Sprung Race Kit combines double ceramic friction surfaces with an ultra - durable Mono - Drive sprung hub assembly in a modular design. It offers aggressive launches and smoother shifting in high - powered AWDs. Each diaphragm spring goes through a four - stage heat - treating process for a consistent light pedal feel. The puck - style friction plates with high - quality ceramic materials provide a high friction coefficient, great heat capacity, and long clutch life. They transfer torque evenly to the Mono - Drive sprung hub assembly, extending input shaft life and reducing driveline shock. This kit includes a CNC - machined and 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. Torque Capacity (ft/lbs.): 1120. Feel: Predictable aggressive engagement, light pedal effort, smooth shifting, possible start - off judder with OE to mild transmission gear noise. Recommended Use: Ideal for Drag, Road, or Rally Racing. ACT Difference: ACT applies tactical engineering to the MOD - TWIN, solving common twin - disc clutch trade - offs. The result is an ultra - durable, serviceable, long - lasting clutch with high torque capacity. All are 100% clamp load tested, balanced, and SFI certified. What's Included: Mod Twin 225 XT Sprung Street Clutch Kit, Xtreme Pressure Plate, Alignment Tool, Flywheel, Release Bearing.
Using this clutch kit is a great way to enhance your 2004 - 2021 Subaru STI's performance. When installing, make sure to use the alignment tool provided to ensure proper positioning. It's also important to check the included components for any damage before installation. During use, you'll notice the light pedal effort and smooth shifting, but be aware that there might be some start - off judder and mild transmission gear noise, which is normal for this type of clutch. For maintenance, regularly inspect the clutch components for wear. Since the Mod - Twin clutches are fully rebuildable, if you notice significant wear, you can order most components separately to get your clutch back in top shape. Remember to follow the proper torque specifications when reinstalling any parts to ensure the best performance and safety.
