Tires are great starting points!
I would do your research on roof racks as there are a lot to there that don't have ideal
load ratings depending on what your intentions are. If I were to reset, I would have done tires and lift first--in lieu of spacers I may have done the
Ironman 4X4 kit.
@jkxranger feel free to check out my
Forester XT build. I realize there is a generation gap here, but there might be something with ruminating over.
