ACT offers several varieties of clutch kits for the 2005-2007 Subaru Legacy GT that provide increasing levels of performance enhancement. Each level of ACT clutch has its purpose, and JSC Speed can recommend an ACT package for your 05-07 Subaru LGT based on the level of modification and purpose of the car. All ACT clutch kits for the 05-07 LGT include a friction surface, a pressure plate, a throw-out bearing, and alignment tool.
The ACT Heavy Duty Pressure Plate is an excellent combination of increased torque holding and pedal feel for most daily driven cars. The HD pressure plate provides 32% increase in clamp loading while creating only a moderate increase in pedal feel thanks to ACT's special, single diaphragm design.
An ACT 4-Puck Sprung Hub Race Disc has very harsh engagement and is designed for road race cars only. A G4 friction surface has good durability and spline life characteristics under normal use. The sprung hub helps to reduce driveline shock and be relatively quiet compared to an unsprung hub but will definitely have chatter. The ACT G4 is SFI certified, so it is legal for all forms of racing that require SFI compliance. JSC does not recommend the G4 for a daily driven/street car.
