    I may be jumping the gun here but just thought I would check if anyone knew this answer. I have a 79 camaro that I found after 17 years of sitting in a pole barn. Now the car did not have an engine in it for all those years of sitting. I am redoing the complete front end and bought the eibach pro kit springs. It says a drop of about 1 inch. I took the old springs out and measured them at 17.5" and the new ones that I just got are about 14". That doesn't calculate to a 1" drop if you ask me....but like I said, thinking I may be jumping the gun. Anyone think that those old stock springs have a different measurement after sitting in the car without motor for 17 years or is this something that shouldn't even concern me with thinking about the 1 inch drop they said for this year stock?

    You are measuring them with no load on them, not a good way to compare springs because they will compress to a different height(under load) depending on the spring rate(strength).

    The new springs are Eibach and the number is ETB-3852-120.

    Greg has it right. Your new Eibach springs are much stiffer than the old stock coils you're replacing. Stiffer springs don't need to compress as far as softer ones do to achieve the correct ride height.
