Makes me curious how a jku with stock axle width and wheels with 3.5" back spaced wheels would fare.
I'd be interested to know as well. For sure, it'd have to be more than 41.20' but the question is, by how much?
BTW, I made a more complete post and with pics of the testing we did and you can see the results here:
