Fitment: This clutch kit is specifically designed for Subaru STI models from 2004 to 2021. Features: The T2S - S05 kit from ACT pairs Mod - Twin 225 clutch discs with a well - loved Xtreme pressure plate. You'll enjoy a soft, progressive clutch engagement with light pedal effort, and it can handle up to 875 ft/lbs of torque on your STI. It's perfect for street use or street/strip driving. This kit combines two organic friction surfaces with an ultra - durable spring center Mono - Drive hub in a modular design, offering great pedal feel, durability, and high torque capacity. Each diaphragm spring goes through a four - stage heat - treating process for a consistent light pedal feel. The steel - backed friction plates with high - quality organic materials provide a stable friction coefficient, good heat capacity, and a long clutch life. They evenly transfer torque to the Mono - Drive sprung hub assembly, extending the input shaft life and reducing driveline shock from torsional vibration. Included in the kit are 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, and alignment tool. Mod - Twin clutches are fully rebuildable, and most components can be ordered separately. Torque Capacity: 875 ft/lbs. Feel: Soft progressive engagement, light pedal effort, smooth shifting with OE to mild transmission gear noise. Recommended Use: Ideal for street or street/strip driving. ACT Difference: ACT applies smart engineering to the MOD - TWIN, solving common twin - disc clutch issues. All products 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 the ACT Mod Twin 225 XT Sprung Street Clutch Kit is straightforward. First, make sure your vehicle is a 2004 - 2021 Subaru STI. When installing, use the included alignment tool to ensure proper alignment of the clutch components. This will help with smooth operation. When driving, you'll notice the light pedal effort and soft progressive engagement, which makes shifting a breeze. Just like with any clutch, avoid riding the clutch pedal for long periods as it can wear out the components faster. For maintenance, keep an eye on the clutch performance. If you notice any changes in pedal feel, such as it getting harder or the engagement becoming less smooth, it might be time to check the clutch. Since most components are rebuildable and can be ordered separately, you can easily replace worn - out parts. Also, remember that this clutch can handle up to 875 ft/lbs of torque, so don't exceed this limit to maintain its durability and performance.
