Wheel back spacing question

[QuicksilverJK]

I ran across a set of 17x9 wheels with 4.25 back spacing. How would this compare to stock wheels with 1.5" spacers that I currently am running? I know the wheels themselves are wider, but I don't know what the actual back spacing is. Just trying to get an idea if it will be wider or narrower than my current setup.

I think the stock wheels are at 6.25 so with your spacers you should be at 4.75. So your new wheels would be a little wider

Thank you, that was what I was looking for.
