I never had a problem with rubbing, but my old wheels on my 34 were about an 3/16th of inch off the edge of my upper control arms. Weights were not a problem as the wheel used the glue on weights (not on the rim). Didn't want to grind down the control arm edge. Fortunately (or unfortunately) I had problems with another wheel so I opted to get new wheels. To correct the problem I dropped my front rim width from 7 to 6 inches and decreased my backspacing by 1/2 inch on the new wheels. Now the problem does not exist.

Since you just got this new set up wheel spacers may be your best hope. The ones on ebay, or similar, may be the best and cheapest solution.
