From a spectator's stand point, you'd have a hard time telling the difference if no one told you to look for it. But from an owner's stand point it's a huge difference. Not really something you can ignore after you see it. If it were me, it would bug the sh*t out of me. It would literally drive me crazy driving the car knowing one of my wheels is thinner than the other on one side.
I do hope you get it solved though. It is a nice design.
