I got eibach springs today and it didnt come with instructions, so i cant figure out which ones go in the front and which ones
go in the back, help me now pleeeeaase

 

Most of the time the springs are marked with an F or R after the part number on the spring itself.

 

On my Eibachs it just had a number. No F or R designation. However, there is a number on each spring that designates the spring rate. You will have to call Eibach to find out which is which. You should have 2 springs with the same number and 2 with a different number. If all 4 are the same then the spring rates are the same.

 

In most of the cases I've seen with S2000 springs, the rears should be the stiffer springs. (although in a lot of cars it's the other way around)

 

thank you every body for the help eibach springs have numbers on them the last number is 1 or 2 one is in the frount and 2 is in the back thank you every body for your help Jason Kasten
