Sorry if I am beating a dead horse, but I have some similar questions. First, I did the 2 inch coil spacer, Z71 coils, and 5100s in the rear and the keys were bumped up a couple inches from where it was so it is sitting level (aftermarket keys installed a while back). I am considering a 16x8 or 17x9 inch rim with either a 285/75/16 or 285/70/17 tire. First question, is it inevitable that you are going to get a rub with these two setups? Nearly every person that I have seen on here seems to get rubbing at full lock with either setup. Second, what would make it more unlikely? Decreasing the offset (negative offset)? Less backspace? Maybe going to a 17x8.5 inch rim, instead of 17x9? If it helps, the 16 inch is 16x8, 0mm offset, and 4.45in backspacing. The 17 is 17x9, -12mm offset, 4.49in backspace. Thanks for any help!
