Bump steer is always going to be an issue on a 6" lifted car. Fixing caster isnt going to magically get rid of it. But fixing the caster will have done wonders.
Check all the bushes in the front, panhard rod, radius arms and tie-rods.

Raise the diff end of the panhard rod mount to level it up you can also get a dropped steering drag link to straighten out the tie rod ends . helped heaps on mine. obviously if you are making the suspension travel from min to max it will still move the steering alignment.

If you are replacing bushes always use genuine!
Bumpstop has nothing to do with the bushes but worn bushes will cause problems like headshake and steering wobble.
