-Gold Line (GPS-0300): 1.5"/2.0" lowering. F)160#. R) 160# variable rate. However, they didn't say what the beginning and ending rates are.
-Eibach Pro (2860.140): 1.6"/2.0" lowering. F)159# linear. R) 91-160# variable. According to Eibach, the rear spring is into the 160# rate at static ride height, so it basically functions as a 160# linear spring.

I have a new hero!! Thanks, this explains a lot. As Sci-Fi posted, if the stock spring rates are 160F/140R that probably explains why I had the rear end bouncing problem I did with the GoldLines and stock shocks, yet the front seemed fine. I'll just bet that the GoldLines start at 160 and get firmer from there, thereby compounding the problem. Probably also explains why people who have installed the Eibach springs aren't as bothered by the problem. If the Eibach rears are a pretty linear 160 then they aren't that far beyond factory, so the factory shocks can handle the task better. I would imaging that the factory shocks may have a shorter life with these springs, but hey, we'll all replace our shocks sooner or later, right?
Thanks guys! This is great information!
