I need to lower my 97 e420 sport. I don't want a harsh ride, which springs are better...the Eibach pro kit or the H & R kit? Thanks[/QUOTE
Eiback and H & R are the same company. The only thing that is different between the two are the ride of the spring, meaning if you use H & R it feels like the same as the "factory ride" which is better and 1 1/2 inch all round.
For Eiback they do it a little bit different, for the front they lower it 1-3/4 and for the back 1-1/2, the ride a little bit harder.
Springs will cost you around $350 or so and labor for E class like 5+ hrs
I don't think Eibach and H&R is same company. If you look at all the threads on this topic here, you will find H&R is harsher than Eibach. I went with Eibach kit and Koni adjustable shocks from www.tirerack.com.
They sell a complete Eibach kit with Eibach shocks, but it's actually more expensive, and tirerack told me Koni is better shock. Here's how my '98 looks with Eibach/Koni and #2 spring pads:
