Springs for my A body
 

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?

Given that you have some Big Meats on your car that Chevy Engineers never even dreamed about, I would say your Roll isn't too bad. Ryan's Spring Rates aren't too far off from ours, so that is correct. but I think Ryan's Springs are better than what you currently have.

What Size are your SwayBars?

Front sway is 1 1/4 rear is 1" Pro Touring bar set on the softest setting per Ramey.
