So my pro x American star tie rods mean I shouldn't have to do anything to correct bump steer? I'm running Mitch's camber spacers to correct the camber.

No, you should move the steerings arms mounted to spindle from being mounted on top of the tab on the spindle, to being mounted on the bottom of the tab. Look at the spindles and steering arms you'll see what I mean. It makes the tie rod run nearly parallel to the arms, reducing the bump steer significantly. The mod can be done on 250's also by swapping the steering arm from one side to the other, so instead of the bend going up, they should be going down, again look at your steering arms and you''ll understand.
