Advance Clutch Technology’s new Mod-Twin Kit is a performance breakthrough for the Evo VIII, IX, X, and Subaru WRX applications. These vehicles are making lots of power, and with great power comes the ACT Mod-Twin.
It is a completely modular design that allows two Street or Race Discs to ride in a single spring-centered or non-spring centered mono-drive hub. The sprung hub will damper the torsional vibration that travels down the input shaft and help extend the life of the splines in the discs.
