Most of the big tire cars around here are four link and ladder bars. Does the pinion angle really change that much on them? I can't see them rotating near as much as a leaf spring car.
Still matters.... you just dont want it going positive ... but the 4-link and ladder bar move about 1* to 2* where a leaf car moves about 6* EDIT I should say... you would like it to line up straight under full power
