Creative Steel’s polyurethane rear subframe bushings for the E55 are a direct replacement for the OEM rubber bushings. The OEM bushings are very soft which make them ideal for isolating noise and vibrations; however, it comes at a cost of reduced vehicle handling. The OEM subframe bushings allow the rear subframe to move effortlessly causing less then ideal handling due to suspension alignment changing while under load. Another problem with the OEM bushings is their tendency to either break the mounting bolts or tear the threads out of the body of the car. These polyurethane rear subframe bushings will help in reducing these failures as the force on the bolts will be less due to less acceleration of the bushings. Our polyurethane rear subframe bushings not only hold the rear subframe in place, they do it with minimal increase in vibration and noise. Most customers will not notice any difference in vibration or noise with our street (black) bushings.

Here is a video comparing a good OEM bushing to our polyurethane bushings
