ACT 04-20 WRX STI Mod Twin HD Race Kit Unsprung Hub Torque Cap 895ft/lbs Not For Street Use

T1R-S07 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.
