There has been some discussion about lowering the E55. There has been talk of removing the pad on the spings/ different pad thicknesses. Where do you get these pads and what is the lowest I can expect to get the car. Will I have to realign the suspension. Is this application for the front as well as the rear. If this is a part from MB where do I tell the dealer to look for the part as my local dealer/shop knows nothing of this.
