Question on what you guys think. I bought my FJ slightly used a couple of years ago. The dealer had installed a Revtek 3" and had 285 75 16 mounted when I found it. I recently installed Warn front and rear bumpers and will be soon slapping on a winch. Should I consider moving to a heavier spring set up like the OME heavies? I just put the bumpers on, and certainly haven't put them to use yet offroad...thoughts?
