I have H&R Sports on mine. When I retained the stock AMG/Bilstein shocks the ride was way too harsh/bouncy. However when I installed the Bilstein Sports w/ Poly shock bushings/stops, the ride improved dramatically. The car is absolutely fantastic on high speed staight runs or wild runs through the twistys.

However, bumps at 40 mph and under are very noticeable and the ride is not nearly as "plush" as some would expect from a Benz. Hell, that's the price to pay for handling. My H&R/Bilstein set up works far better than the AMG stock set-up and gives me a lot more confidence in the corners and it has almost eliminated body roll.

I've heard that Eibach's are a little softer and give a better ride but a Benz performance tuner told me to stick with the H&R's as they will work much better at high speeds.
