I went with trailready 17x8.5's and 3.5 backspace. Seemed to be the better choice especially since I already have the toyo 40x13.50's I need to start a build thread with pics/specs at some point. Once all this starts coming together I'll get one going

I have a 79 ford 60 with 17 racelines with 3.75BS and 40 toyos and zero rubbing roughly 4.5 inches of lift. I also ran 40x14.5 KM2s on spyderlocks with no rubbing either.

Backspacing

I just installed the Spicer ultimate 60 under my 2015 JK unlimited. I have the Trail Ready Beadlocks 17 X8.5 with 4.5 backspacing and it works great with 37 in BFG Krawlers. The brake calipers on these things are huge, my weights on the wheels rubbed barely but ok now.
