Dumb question... Probably not related the the OP's post, but does the location of the front spring eyelet, on other words angle of the front leaf segment to the ground or chassis, have an affect on axle rotation with a cal trac?

I'm know with a ladder bar car lowering the front heim into a lower adjustment hole Softens the hit on the tire, and vise versa, raising the heim attachment makes it more violent on the tire
