FWIW, I have the M&H's mounted on regular GTA fronts (16x8) with no rolled lip. On the street I run a 3/8" spacer to push the tire further out into the GNX flare and have never had the DRs rub on the street. This last time back from the track when I pulled off the wheels to put the spacers back on, there was a small area of paint rubbed off on the frame from the tire, but nothing too bad and it was only on the drivers side.
