The only thing that rubbed was the carpet liner which I tied back with some zipties. My truck came with the aluminum control arms and have not noticed any issues. To be honest I didn't notice a big difference lugging around more rotating weight, either but should probably mention I have a blackbear tune as well. I ended up w/the BFGs mostly due to the fact they were the lightest AT tire I could find in that size, plus 4WP had a special during xmas a few years go, so it was a no-brainer.
Attaching some pix for reference.
