From the pictures your car appears to ride a bit lower than mine. I don't believe the Eibachs will get you where you want to go unless they are stock springs. What size and make tires do you run? With low profile tires your ride will tend to be harsh regardless of the spring and shock combination. I know what you mean about punishing ride...I thought my 2001 E55 rode very harsh on US roads (but the ride was perfectly acceptable on German and Italian roads). If I had to live with your roads I think I would either install stock springs (or MB sport springs but you should check with the performance paddock part of this web site to see if they are less stiff than Eibach or H&R springs), leave the Bilstein shocks alone and install uprated (H&R) antisway bars if not already fitted to your car. You will get a much more compliant ride and still reduce the leaning in the corners. I doubt that with your roads you will be happy with the handling/ride compromise offered by aftermarket springs. I definitely don't like floaty/squishy suspensions but I was pleasantly surprised by the handling/ride compromise of my 2001 Wagon with 60K miles with the original springs, shocks and antisway bars. Well controlled (like the old air suspension MB's) but not harsh. IMO much better than my 1991 300TE when it was stock and far superior to my father's 1995 E320T after replacing all the suspension bits with new OE components. Mark
