This ACT HD Pressure Plate is the only other option you have for your Spec Miata according to the SCCA and NASA rules. This is the same one you will get from Mazdaspeed, why pay tax and shipping? Get set up with us!
Here are some reasons why the ACT PP is better than a stock PP:
Diaphragms are induction hardened on the release bearing contact area to reduce wear and promote smooth operationCover stampings are sometimes reinforced by ACT to reduce flex and improve the efficiency and feel of the pressure plateStronger drive straps and rivets are used when needed to strengthen the pressure plate and prevent breakageWe load test every pressure plate on a special computerized testing press for quality assurance. This same machine also assists in designing new products and evaluating parts that are in for serviceProper release travel, clamp load, pedal effort, and working range are analyzed using specialized testing equipment and softwareAll castings are CNC machined for greater consistency and precisionACT pressure plates feature a special single diaphragm design to dramatically increase clamp load without the adverse affects of double diaphragm type clutchesPrecision cover stampings provide rigidity, consistency and are cost effectiveCreative diaphragm designs are used to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure an exclusive four stage heat treating process for unparalleled performanceMost ACT pressure plates are certified as meeting SFI Specification 1.1. and are legal for competition in all racing organizations where SFI certification is requiredAll ACT pressure plates are dynamically computer balanced for smooth operation at high rpm
Is that enough proof for you?
