The OEM wishbone engine mount on the Ford Fiesta ST 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.
