My '91 300E with 168k miles, just had its rear springs replaced with stock MBZ springs.

The rear suspension was hitting the bump stops with passengers in the rear seats. The results are great! Car feels balanced and the ride seems to be improved AND no more hitting full compression on the suspension. Very glad I did this.

Question: Does anyone have any experience with how much this rubber collars compress over time? I did not replace the rubber collar between the body and the spring. It is a three bump collar. The rear is just a little lower than before. Would replacing the collar with a fresh one really make any difference? Instead should I A) replace the collar with a four bump? B) just replace the old three bump collar with a new one? C) possibly replace the front springs two bump with a one bump and lower the front end slightly and get the weight transfer?

Hopefully this isn't too confusing.

Thank you in advance-
