20s help

i want to run 20s all around on my 98 frontier.what would a good offset or back spacing be for me since im laying frame. i plan to stock floor it next year.

I would look for at least a positive offset of 35mm for an 8" wide rim.

mine are 20x8.5 with a +40mm offset and i had to trim the fender lip but the tuck

yea what pugzli said.... nice wheels man im running the same shit, still on 6 lug
