It is well known that the stock rear motor mount on the MPS3 is a weak link and CP-e has chosen to think outside the box on this and come up with a completely new design. To do this CP-e carefully studied the layout of the stock MPS3
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 7.17Kgs are
slowly whittled down over the course of a couple of hours in our CNC
machine to a final weight of 1.60Kgs. This process takes a lot of
time but was necessary to give our customers what they want.
