Sounds like he knows what it is, and what causes it, he's just wondering how much other rodeo drivers have. Great post though, now I know what he's talking about.rollintroopers said:Jwood, yours is flapping out because you've lifted your rig and the upper control arms are pointing downward at ride height. when the bump pushes the tire up into the wheel well the arms straighten straight out, which causes positive camber. Looks crappy but its harmless. You should have bump steer along with it.
