Fitment: This clutch kit is designed specifically for 2004 - 2021 Subaru STI models. Features: ACT's T3R - S07 kit comes with a Mod - Twin 225 XX Rigid Race clutch. It offers predictable aggressive engagement, more pedal effort for quick shifting, and can handle up to 1340 ft/lbs of torque on your STI. Ideal for drag, road, or rally racing. The Mod - Twin 225 XX Rigid Race Kit combines two ceramic friction surfaces with a solid Mono - Drive hub in a modular design, perfect for aggressive launches and rapid shifting of high - powered AWDs. The diaphragm springs go through a special four - stage heat - treating process for a consistent pedal feel.

They transfer torque to a heat - treated Mono - Drive chrome - moly hub, extending the input shaft life. The lightweight and rigid design allows for fast shifts and hassle - free service. This kit includes a CNC - machined and balanced flywheel, pressure plate cover, diaphragm spring, face, puck - style ceramic friction plates, rigid Mono - Drive hub, floater, patented Monoloc Collar, release bearing, alignment tool, and pilot bearing (if needed).

Using your ACT Mod Twin 225 XX Rigid Race Clutch Kit is straightforward. First, make sure you've got the right fit for your 2004 - 2021 Subaru STI. The kit comes with all the necessary parts, so just follow the included instructions to install it properly. When driving, expect a more aggressive engagement and increased pedal effort, which is normal for this high - performance clutch. It's great for quick shifting, but be aware that there might be a bit of start - off judder and some mild to moderate transmission gear noise. This is part of its racing - oriented design. As for maintenance, since the clutch is fully rebuildable, you can order most components separately if they wear out. Check the clutch regularly for signs of wear, like reduced pedal feel or slipping. Keep the clutch clean and dry to ensure its long - lasting performance. And always remember to follow the safety precautions in the installation manual to avoid any accidents.
