Well guys, the transformation of my e320 wagon suspension to the e500 set up is finally done. In addidion to the suspension I chose to put on 17 x 7 enkie wheels with toyo proxies all around. The characteristics of the car have completely changed. There is little to no body roll, the ride is firm yet still soft only as a Mercedes can be. The overall ride quality and feel for the road is approaching that of my 2003 e500 sedan! What a difference. Thank you all for your input and expertise.
