Mazdaspeed3 RMM Stage 2
It is well known that the stock rear motor mount on the MS3 is a weak link and cp-e™ has chosen to think outside the box on this and come up with a completely new design.
- Billet CNC construction
- EPDM Bushing to protect rubber from overheating
- Stainless Hardware
- Vertically mounted bushing increase’s durability.
- Machined additional pockets to create lightweight but strong mount.
- Step by step installation directions
To do this cp-e™ carefully studied the layout of the stock MS3 Engine Mounts. While designing the side engine mounts it was determined that a better design could be achieved on the rear mount as well.
The way the Mazda engine mount system works is that the two side mounts provide a rotational mounting point, if just these two mounts are installed without a lower engine mount the bottom of the engine is free to swing like a pendulum. Now if you take the stock engine mount and put it in place with its horizontally mounted bushing and you apply some power, it will stop the engine from swinging but you are now stressing the bushing in two directions. These types of bushing are not really meant for this.
So cp-e™ came up with a way to stress the bushing in only one direction, by remaking both sides of the engine mount cp-e™ was able to mount the bushing vertically so now the pendulum affect of the engine is stretching or pushing in only one direction. This also increases the durability of the engine mount substantially.
To accomplish this two blocks of aluminum, starting at 15.81 lbs are slowly whittled down over the course of a couple of hours in our CNC machine to a final weight of 3.53 lbs. This process takes a lot of time but was necessary to give our customers what they want.
