ACT Heavy Duty Race 6-Puck Solid Clutch Kit Mazdaspeed3 2007-2013 / Mazdaspeed6 2006-2007


ACT 2007 Mazda 3 HD/Race Rigid 6 Pad Clutch Kit


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.

Modified Street Disc

ACT’s Modified Street friction surface is SFI certified and is an excellent choice for lightly modified, street driven cars. The MM disc provides quicker engagement than a stock surface and is quiet compared to other, more aggressive, friction surfaces. The sprung hub uses bushings and cone springs similar to OEM clutch disc; this creates frictional dampening which improves clutch life and reduces noise.

6-Puck Solid Race Disc

The reduced inertia of the ACT 6-Puck Solid hub allows for very fast shifts at the expense driveability. An ACT R6 race disc friction surface has very good durability but will have shortened spline life. ACT designed the R6 for a highly modified track cars where harsher engagement is expected and some clutch chatter is not a problem. The 6-puck layout of the R6 will absorb, and disapate, more heat than a 4-puck unit. The ACT 6-Puck Solid Hub Race Disc is legal for all forms of racing that require SFI compliance. IIR does not recommend the R6 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.
