Help me confirm my measurements and back spacing thought

5.5" and a spacer won't work. If you want to use a spacer you'll need more, not less backspace. I'd be looking for a 6" backspace honestly, I know you won't find a 5 5/8" unless you have them custom made and that 1/8" will be important to the quarter lip.

I'm sitting here still trying to figure this out. So I drew it out. In my mind it looks like a 5.5 backspace will put the tire on the spring and a 6" would be worse .i attached a picture and drew it out. Take a peek and let me know if my thinking is wrong.
