Focus ST RMM
Custom Performance Engineering, Inc. has chosen to think outside the box on this and come up with a completely new Focus ST RMM design. To do this, cp-e™ carefully studied the layout of the stock Focus ST rear motor mount. Immediately after removing the rear mount it was decided that a better design could be achieved.
The Ford Ecoboost engine mount system contains two side mounts that provide a rotational mounting point. The rear motor mount is added to help prevent the engine from swinging like a pendulum. However, the design of the stock mount orients the bushing horizontally; allowing applied stresses to act along two planes in the bushing. These types of bushings are not really meant for this and it has been found that the rear mount may be inadequate in preventing the engine from moving.
