your caster is out of spec. as you shim out the arms, you push the bushing that connects the thrust arm out (caster arm, tuning fork, etc.) and pull the wheel assembly forward as a result (thrust arms are not adjustable). if you look at your car you'll probably see the wheel sitting forward in the wheel well. depending on the width of wheel/rubber/spacer/offset you are running you might get some rubbing too.
here is a thread on how to fix; involves swapping the lcas and using the other opening in the thrust arm bushing:

or, if no rubbing, you may be happy with how the increased caster impacts your handling.
