Features:
ACT’s T1R-S07 kit features a Mod-Twin 225 XX Sprung Race clutch paired with the every popular Heavy Duty pressure plate. What does this mean for you? Well, that means that you will have predictable aggressive engagement, light pedal effort with quick shifting and the ability to handle up to 895ft/lbs of torque on your STI. This clutch kit is best suited for drag, road or rally racing
The Mod-Twin 225 HD Rigid Race Kit tackles aggressive launches and rapid shifting of high powered AWD’s by combining twice the ceramic friction surfaces with a no-nonsense solid 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. Puck-style Friction Plates with high quality ceramic friction materials deliver high friction coefficient, superior heat capacity, and long clutch life. These Friction Plates uniformly transfer torque to a Mono-Drive chrome-moly hub which is heat treated for strength and durability extending input shaft life with one continuous spline. The lightweight, rigid design allows for quicker shifts and trouble-free service. This kit includes a CNC-machined and dynamically 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). Mod-Twin clutches are fully rebuildable and most components can be ordered separately.
