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).
Black Forest Industries engine mounts are designed to replace your old, soft factory engine mounts. BFI's mounts feature a proprietary bushing and bracket/cup design, maximizing bushing area while minimizing vibration to give your BMW the best ride characteristics possible from a urethane bushing mount.
