Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).
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 occurring in your vehicle, it's time to examine your mounts. This motor mount is one step towards repair. This mount will function and fit just like stock and 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. This mount is of stock hardness and will restore a factory-type feel.
