So I decided to replace my shocks on my e300. I have only changed the front so far. I decided to go with the b6 upfront because I read it's 20% firmer over stock and the b4 is 10%. I noticed the shock is little shorter and really seems to help with body roll. But it is a harsh ride. I was looking for more plush, I can still return these and throw a set of b4s up front. Just looking for input.
