Fiesta ST Rear Motor Mount
The OEM Fiesta ST Rear Motor Mount is a known weak link. One of the biggest issues is the OEM rubber that will flex too much, hindering performance during spirited driving. cp-e™ has taken their knowledge and experience with motor mounts, and put it to solving this issue on the Fiesta ST; reducing wheel hop, engine movement, and the performance robbing effects that the stock mount allows.
cp-e™ goes a step above the rest by using an EPDM bushing; a type of rubber. Urethane begins to fail at temperatures as low as 200°F and generally the bushings need a higher durometer rating to hold together. The Fiesta ST rear motor mount is a perfect example of when not to use urethane as many companies do. The location of the mount allows a large amount of heat to be transferred to the bushing. EPDM holds up to this heat, and doesn’t begin to break down and fail. To top it off, EPDM has a higher density than urethane, so the bushing can have a lower durometer rating while keeping high reliability and support. Why is that good? A higher durometer bushing would transfer more vibrations through the vehicle and into the cabin, raising the NVH (noise, vibration, & harshness) value.
All components of the mount is CNC machined out of billet 6061-T6 aluminum and designed to bolt into the stock location without any modifications to the vehicle. Anodized black, and laser engraved for a clean look, the mount assembly is a sure eye pleaser; making you smile every time you change your oil!
Because the new design is more rigid and flex’s less you will experience less wheel hop and engine movement with spirited driving; lowering those lap times at your weekend track days! Essentially, the engine mount allows the car to “hook up” better, and allows easier, more precise shifting.
Unlike nearly all other engine mount manufacturers, we use EPDM for our bushings. This provides much more vibration resistance when compared to polyurethane. This material is also extremely resilient and is able to stretch and even develop small cracks without affecting its structural integrity. EPDM is much more expensive to produce, but it is a far superior bushing material.
Pressed Center Insert
Our metal inserts are physically pressed into our EPDM bushings. This allows the bushing material and the metal to have a perfect connection without any gap. Other manufacturers cut their material out to fit, leaving small tolerances where the metal can still vibrate. Our construction allows the EDPM to absorb the vibrations and allows the metal inserts to smoothly move with the EDPM.
