I'm running 315's right now with 2.5" AEV which netted me slightly over 3". With new used soft top I'm not sure I can fit 37's into my garage with more lift. I was thinking of just chopping and then stuffing 37's and adding a 1" BL if necessary.
You won't be able to clear 37's with just 3" of lift EVEN IF you chop your fenders. Even with a lot of trimming of the body, I can barely clear my 37's with 3.5" of lift. In other words, even with a 1" body lift will help you get there, you will still need to do some body trimming and your soft top will still sit 1" taller on top of whatever your tires give you.
