I remember not that long ago I was watching a video of Mark Stielow thrashing Hellfire around a road course and you know what I heard...a tire rub a fender on certain bumps... Several times in fact. I guess it happens to the best of us.
I didn't laugh or look down at him when I heard that, I nodded approvingly...
Because I knew he was trying to get everything he could out of the setup and was apparently willing to deal with a rub here or there as a compromise.
IMO, if you are the type of owner or driver that doesn't want to deal with that, put a smaller tire on the car. Or...spend a WHOLE bunch more money on an aftermarket sub frame that will let you run that tire without it rubbing...maybe.
