Are the Eibach REAR springs the same for both impala's and 9c1's?
if different, what kind of drop height should i expect roughly with each spring?
(i do realize that eibach springs are inaccurately made and may vary from applications to application)
Sam I don't know if there the same but mine dropped 1.5 in the back and the front about the same. My buddys set dropped over 2 inches and in time he have to replace them because the tires were rubbing. Which Eibach replaced them with no charge.
