Hey guys i'm running 18x9.5 all around with 225/35/18 tires, I dont have a problem with the wheels rubbing on the fender or the inside of the wheel well i'm slightly tucking tire all around but not too low, the problem is if I go any lower up front my wheels hit in the very top of the wheel well, seems to be a metal bar that it hits on is there any way to gain more clearance or do I just need to get 17's?
Same issue with the rear, yes I have all of my fender liner removed its hitting the actual metal
