have you done a "tire on and suspension at full compression" turning test to ensure the rubber doesn't tear a fender off when turned all the way and the suspension bottoms? with the spacers the tires do more of a sweep during a turn so they may get closer to the wheel openings than you may realize. it would suck to find that out too late.
I am sure you have done the research and found the video on scrub radius, tire size and wheel offset issues and steering included angle etc. your truck, do it like you want. as long as it is safe to drive on the same roads as the rest of us and our kids.
