I have a 97 C280 w/ 18" rims, 225/40/18 tires front and back.

I dont know whether to lower my car with H&R or Eibach Pro Kit. One is 1.4/1.3 inches and the other is 1.2/1.2 inches. Do any of you know whether one will look better? whether one is better quality? should i just go with price?

 

I'd go with Eibach Prokit. They are the 1.2 in. drop, right? I don't have any experience with H&R, yet I understand they are good quality.
I've had the Prokit springs and they give a lowered look, with better handling and yet not harsh.

 

is that a picture of your car with the Eibachs on your Avatar? because that one looks more lowered than 1.2 inches, but if thats what it looks like im in!

also, does anyone have pics of cars lowered with each, preferably c280s with 18" rims =P

 

No. That is a C43. I have a C280 S.
It is pretty sweet. I used a Sachs Performance Set on a Ford Focus. The Performance Set used Eibach Prokit springs with Sachs shocks
Your would proly be more interested in Eibach Sportline springs - 2 inch drop- but I don't believe Eibach makes Sportlines for the C280?

 

go for the one with the bigger drop, they will look the best imo :-)

 

go for the Eibach Prokit.

 

How about the H&R cup kit? It's expencive but it's a 2 inch drop in the front and a 1.7 inch drop in the rear. I'm thinking about doing that with mine and I've got 18x8 in the front and 18x9 in the rear.

 

Eibach Pro Kit will provide 1.2" drop (front and rear).
Eibach Sportline Kit is not available for W202 C280.
H&R Springs will provide 1.4" and 1.3" drop (front and rear).
H&R Cup Kit will provide 2.0" and 1.7" drop (front and rear).

 

Eibach is bad!!! Ive had Eibachs, H&R sport springs, and Volgtlands on my car.

THe best is Hands down H&R! Eibachs bounce around and tend to sag after a year.

Volgtlands just dont drop enough!

H&R is perfect! height, ride, no sag best quality!

 

For Mercedes, H&R is more popular than Eibach in general.
So it is a wise decision to choose H&R. But that doesn't mean Eibach is bad. Even Ground Control uses Eibach.
It's a matter of personal preference of how you want your ride to be.
