Hi guys,

I would like to ask would the Eibach Sportline springs (for Sedan) fit on the stock sport struts? I realize that there are two sets of number indicating the harshness of the springs:

Eibach G35 Sedan sportline progressive springs 1.6"/1.6" drop
F: 171/400 R: 285-502

I realize that the first one would be the initial rate, the latter one would be the final rate.. So does it mean that I need to change the struts to handle the "400" and "502" stiffness for the springs? I know that the stock struts could handle the initial rate for sure, but do I need to care the final rate?

Sorry if I ask the dumb question, but I already search for the whole forum and there are few topics cover both rates on the same spring.

Thanks!!!

 

What'd you decide? I'm in the same boat as you. I think sport should be able to handle it.

 

Anybody??

 

I thought the rule was more than an inch of drop, buy new struts.
