Excessive driveline vibration is caused by one of a few things, but more than likely, it is the mounts in your vehicle. They keep your engine and transmission secure for more positive shifting and driveline triangulation as well as absorbing vibration. If any of these are occuring in your BMW, it's time to examine your mounts.
This motor mount is one step towards repair. Made by FEQ, this mount will function and fit just like stock. Not only will it fit great, it will absorb those nasty vibrations, quieting your cabin and reducing vehicle shake.
Take a look at your other mounts prior to ordering. Grab your engine by the top and shake it. If it moves rather significantly, replace all the mounts to stiffen up your entire driveline for better performance.
