Hey guys, I just picked a super clean 2010 Sahara with only 48k! This is my first experience in the Jeep world, and I'll be honest, all the modification options are a little overwhelming. Currently its sitting on factory 18's with new 255/70/18 AT tires. I understand that this was the factory size and measures at a little over 32" tall. Personally I'm happy with the look, but would like to see if I can "widen" the stance a little. If I was to buy spacers and install them is that something that is ok to do with stock wheels? Also is it common to do them front and rear, or are they only made for front? Please forgive my ignorance! I really look forward to learning more!
