I've found these cars extremely intolerable of any wheel and tire issues, not to mention the brakes. I agree it may be beneficial to redo the rotor/hub mating, but I wouldn't hesitate to swapping the wheels back to their original position afterwards if that did not resolve the issue. If the brake work is not the culprit, then by elimination the wheel swap is. That being the case, I would have the wheels and tires broke down and remounted so the tires maintain the prior direction and the wheels are reversed to the correct rotation. Regardless, during the tire/wheel swap I would then have a high speed balance performed.
