have the same problem with my 190d. I replaced front struts with Bilsteins from Performace Products and the car began to ride 2 inches higher. replaced the rear ones with Bilsteins from the benzbin and the ride height did not change. Now, I noticed that my rear tires cut the outside edges, indicating potentially the wrong ride height. i wonder if the wrong struts would do this. To the best of my knowledge the car rides on springs and the height cannot be controlled by shocks. I did nothing else to the suspension (springs were on the car and not even depressed during the strut change).
