Hey guys, I recently went up to 37s and looks like my fears are reality. I'm running 17x8 level 8 trackers that have 4.25" of backspacing which looks like it's not enough to clear my 37x12.5 hankooks so it's time for some spidertrax. I'm currently rubbing on my frame and metalcloak LCAs. Anyone know roughly the best backspacing? I've read that 4" and below seems golden. I was thinking either 1" or 1.5" spacers. Are there any major downsides to larger hub centric spacers?
