Recenly put some low profile tires and wider weels on my 1992 400E, I'd also like to replace the stock springs and shocks , perhaps lower the car's center of gravity a bit. I don't know where to start. There are so many posts on this subject I'm a little confused. Does anyone offer a complete kit for a 92 400E? or can anyone reccomend a complete set of springs and shocks and etc....
