The Fiesta ST has a unique problem with rear motor mounts. The problem is the mount is very close to the downpipe. Well that area gets very hot and polyurethane does not do well with extreme heat. The heat softens the polyurethane making it more susceptible to stretching or tearing. This is more likely to occur with the softer polyurethane engine mounts which are more popular because they do improve shift feel, but also don't add too much vibration. Luckily you have two choices available for upgraded rear motor mounts that are not polyurethane. This includes CPE, and vibra technics which is what I installed. Vibra technics also comes in two versions fast roads, and competition. I installed the fast roads version which is the softer of the mounts.
