Every since we brought the '10 GT500 home there has been a sporadic rubbing sound when making a sharp turn. It doesn't happen all the time and of course didn't make the noise when the car was taken to the dealership to have it looked at. The outside air temp doesn't seem to affect it one way or the other nor does the temp of the car affect it so I'm having trouble pinpointing what the culprit is. It sounds almost like a rubber on rubber sound.

Anyone have any ideas what it could be, what to look for or what to check out? TIA

 

Those are big tires and wheels in those wheelwells, very well could be the tire rubbing inside the fender since you say it only does it on turning.
