Today, While performing the typical GT owner "anal" cleaning routine I discovered what I believe to be evidence of the outside edge of the rear tires rubbing on the outside portion of the clamshell inner fender. The evidence was a black, carbon like deposit on the outer 2 inch section of the clamshell inner fender and some fine "scoring" on the outside edge of the rear tires where they may have come into contact with the aluminum edge of the clamshell as it wraps around the plastic inner shell that forms the inner fender wheel well. The "carbon residue" cleaned off, but actually came off in chunks like shreaded rubber tires. I am fairly certain that the rear tires are rubbing their outside edges on the inner fender and that it probably occurs during "hard acceleration" :banana . Has anyone else noticed this phenomenon?
