Wotcha people. I'm in the process of potentially getting some rear springs made for my 58 Special, i want to lower it by at least 3 inches in the rear, the company who make the springs is suggesting i consult with a spe******t first, to find out if i need to modify the front suspension as a result of lowering the back. I thought i'd come here and ask if anybody has lowered their buicks JUST on the back end, and whether they needed to change the front. Any help would be greatly appreciated. Cheers.
