I have a W210 with H&R springs only at this time with 19" rims. The handling is great. With the OEM 17" rims, the ride is very smooth. With the 19", it is firmer but still good. My wife enjoys the ride with the 19"; a flatter, more neutral feeling in turns.

I will eventually change the shocks to Bilstein. But for now the ride is good.

H&R's has a lifetime warranty whereas Eibach is a few years. Both are good and you cannot go wrong with either one.

I hope this helps.

Eric
