I put a set of Eibach springs in my 530. They lowered the car by about 35mm, but, it is as hard as a rock. If my drivers seat didn't have springs in it I wouldn't have any teeth left. Also, the car didn't have a rattle in it. I spend all my time now banging the ash tray back and holding up the glove box lid.Originally Posted by kraulto
After I stuck these in someone told me that you can get lowered springs with the same poundage as stock springs - probably best to go there. Gotta say though that the car does go round corners a lot quicker then it used to.
