Default Spring Question
I just bought a set of eibach springs from forum member my question is how do I tell the diff in front or rear. I noticed a pair is slightly higher than the other, I'm thinking those are the fronts but not sure. thanks

They should be the same size. What's the numbering on the coils?

The spring rate should be printed on each spring. the higher spring rates go on the rear

Ah, I see what he's saying. He shouldn't have just said "higher," since these things come in different heights and spring rates. For instance, you can get an 8" tall 700 lb-ft spring, or a 10" tall 700 lb-ft spring.

Is this a COILOVER spring or a stock replacement spring?

V1 or V2?

I think eibach calls them Pro Kit?
