It is well known that the stock rear motor mount on the Mazda3 and SPEED3 is a weak link. We have spent a lot of time studying the motor mounts on the Mazda3 and now have another option for those pushing their cars to the limits. We now offer the cp-e™ Mazda3/ MazdaSPEED3 Rear Motor Mount Stage2. The Stage2 version of this mount will provide more performance and durability with only a slight change in vibrations from the Stage1. You read more about this new mount here. With the release of the Stage2 mount we are also lowering the price on the Stage1 mount to $139.
