My right rear was rubbing on both the fender liner as well as the gas filler under very gentle driving. I wouldn't know for sure if these were OK until some high speed maneuvers so I think I still need to pass on them.
Will, to close the loop on the wheels, I don't think I can use them because of the RS4s. I wasn't able to use the 245/40-18s I bought and, even thought the 17" are an inch smaller diameter, I am afraid they would still rub on my setup.
Good luck with them,
