no rubbing what so ever. About 1.5 inch of room between control arm and tire. Also 8.5 tire fits perfect on the stock 17x8. No cupping at all and tread makes complete contact with the ground. This was a worry of mine as well but once we got them on there and cranked the torsion bars no rubbing. My friend has been doing tires for a long time and he told me it would fit but I was unsure but all is good !
