Custom Performance Engineering offers the first aftermarket EPDM (ethylene propylene diene monomer) rubber engine mount for the Mazda 3 / MazdaSPEED 3! 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.

The CPE mount is unique compared to competitors mounts both in form and in function. We use rubber for the bushing as opposed to urethane simply because it is better suited for this application. Rubber withstands engine heat much better then urethane, and it will not deform or crack over time the way urethane can. CPE was 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 60-durometer bushing absorbs annoying vibrations. Now you can combine the stiffness of a race mount with the comfort of a stock unit!

The motor mount will be offered in two degrees of stiffness, 60 durometer and 75 durometer. We recommend 60 durometer for most customers, but if you want extra stiffness at the expense of some vibration, then you should choose 75 durometer.
