ACT Heavy Duty Race 4-Puck Solid Clutch Kit Mazdaspeed3 2007-2013 / MazdaSpeed6 2006-2007 (Streetlite Flywheel)
All ACT clutch kits for the 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 Solid Race Disc
The ACT 4-Puck Solid Hub Race Disc is legal for all forms of racing that require SFI compliance. The biggest benefit of the ACT 4-Puck Solid Hub Race Disc is its extremely fast shifts thanks, in part, to its reduced inertia. An ACT R4 race disc friction surface has good durability but will have shortened spline life. ACT designed the R4 for a heavily modified drag race or road race cars where extremely harsh engagement and clutch chatter is expected. IIR does not recommend the R4 for any road going 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.
