ACT Heavy Duty Street/Strip 4-Puck Sprung Clutch Kit Mazdaspeed3 2007-2013 / mazdaspeed6 2006-2007
ACT offers several varieties of clutch kits for the 2007-2009 Mazdaspeed3 that provide increasing levels of performance enhancement. Each level of ACT clutch has its purpose, and Import Image Racing can recommend an ACT package for your MS3 based on the level of modification and purpose of the car. All ACT clutch kits for the 07-09 Mazdaspeed3 include a friction surface, a pressure plate, a throw-out bearing, and a alignment tool.
Heavy Duty Pressure Plate
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.
4-Puck Sprung Race Disc
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. IIR does not recommend the G4 for a street driven car.
These clutch kits will not work with the stock Mazdaspeed3 flywheel. All ACT clutch kits for the Mazdaspeed3 include the ACT streetlite 16lb performance flywheel.
