I put Eibach springs on my 250 at 18k miles and kept them paired with the stock shocks. I'm now over 92k miles on the setup and the shocks are going Fast!

I'm planning on F-sport shocks, but do I need to replace my Eibach springs as well?

 

They should be fine.

 

no you should only have to replace the shock/struts.

 

btw, what are your dead shock symptoms?

 

HOLY JEEBUS 92K?! The springs should be fine. I've heard and read good things about the F-Sport shocks.

 

Don't the Eibachs have a lifetime warranty for the original owner....

 

i think i read something about 1 million miles. LOL

 

Yep, but only applies to orgininal owner, and they can easily estimate how long most owners keep the car (probably something like 3 or 4 years on average).
