Collapsing and worn engine mounts can mean big trouble for BMW's. The stock mounts are filled with fluid that can leak or evaporate over time. That leaves the mount unstable and too flexible to properly support the engine. The side effects of a worn engine mounts are: shaking and vibrating engine, driveline twist from engine torque that can break or snap bushings, and broken motor mount arms and bolts. If you're tired of replacing engine mounts you'll be very pleased with these solid rubber versions.

Not only are these more reliable than stock fluid-filled mounts, they are slightly stiffer than new stock mounts thanks to a solid rubber construction (no voids in the rubber) but designed for street use so they remain quiet and comfortable. The solid rubber has less deflection than a stock mount, so no wasted engine motion. Less wasted motion gives you more torque to the wheels (it's not spent twisting the engine) and better engine response.
