Bump steer

Yeah, take my car for instance. Bought it with H&R springs and it has definite bump steer. It's lower than I prefer, but it was a good deal. My plan is to eventually get coilovers and raise it a fair amount. You could also see if anyone offers bump steer correction kits.

Bump steer is not an alignment or tire issue, it is a suspension geometry issue due to the control arm and steering arm not scribing the same arc. As the wiki article says, to dial out bump steer you have to change the position of the steering rack or the outer end of the tie rod vertically.
Here's a bumpsteer kit for my Mustang. The spindle is drilled so that a normal bolt can be used (rather than the tapered stud that is on most outer tie rods), and then the spacers are used as necessary to get the tie rod and lower control arm to scribe the same arc. (Basically, you want the steering arm to be parallel to the line from the inner control arm pivot to the ball joint pivot.)
