I just can't see the front wheel rubbing anywhere on the car unless your fender liner is seriously malformed. I have aftermarket coilovers with a 1.5 inch drop and -2 camber up front,...... with no rubbing issues. All the auto-x'ers here don't report this either with stock ride height, lowered cars, wider tires, more aggressive camber, etc.
You can see my car here .

Check the inner fender liner for rub marks. That should be easy to see. Diagnose the problem more, only on left turns? Only when pushing the car or all the time? Can you tell which side it is coming from? Both? Jack up the front and turn the wheel to full left lock and look for yourself. Spin the tires. Look for anything out of place.
Good luck. Dealers tend to often suck IMO (but not a few here.
