Trying to figure out what springs and or rates I should go with on my 71 Chevelle? I currently have Eibach Pro kit and am not happy with the body roll at all. I have all UMI suspension with Viking shocks otherwise. I talked to Ryan at UMI and thought about trying there coils, but I think they are 550 front and 150 rear. I believe that is about the same as I got now? Does anyone know what spring rate Eibachs are? I was looking at Hyperco coils at Speedwaymotors, but will need adjusters for the shortness of the springs available. I was thinking 600/650 front and 250 rear?
