first taking the clamp off the stock spring lets them work better.you don't do it with s/s springs 7degrees is a good start just make sure you rear shackles are back if that makes sense.you want the back hole in the spring back farther then the one in the frame the shackle should be at an angel something like a 45deg.and be sure to check with car on the ground or with jack stand under rear housing and lower control arms.the more angel the more they will move and thats a good thing.........its always worked for me.with all that she should carry the wheels........Artie
