Custom Performance Engineering is very proud to release the first aftermarket EPDM (ethylene propylene diene monomer) rubber engine mount for the MazdaSPEED3! CNC machined from a single piece of billet 6061-series aluminum; this mount is not only totally indestructible, but it also transmits far less NVH (noise, vibration and harshness) into the cabin than comparable mounts.

Our mount is unique compared to our competitors mounts both in form and in function. We use rubber for the bushing as opposed to urethane simply because it’s better suited for this application. Rubber withstands engine heat much better then urethane, and it won’t deform or crack over time the way urethane can. We were also able to incorporate a unique method of holding the mount in the vehicle. Instead of placing all of the force on the center bushing pin, the load is distributed throughout the bushing. This increases the effective stiffness of the bushing under engine loads, and the bushing absorbs annoying vibrations. Now you can combine the stiffness of a race mount with the comfort of a stock unit!
