Bump steer question

In the stock car world we got the camber where ever we needed it for the track, got the caster where ever we needed it, and the toe and we always got 0 bump steer. We did it be shimming the outer tie rod up or down. It's not that hard if you do it alot like every race day, the car always got hit, jammed into the wall or something. You learn how to do it. So you guys that say it can't be done are wrong. It is a lot harder with tapered tie rod ends but with hiem joints its a lot easier.
