Wheel spacer stud length question

I have a 2015, is 1 inch enough to clear the studs? I know the most common is 1.25 spider trac but I would rub really bad with that

 

I have 1" bora spacers and they clear. I think that is as slim as you can go with the stock studs, but am sure someone will correct me if I'm wrong.

 

how much offset you rocking? With 1 inch spacer it would put me at -10.4 on 275/70/17 with 2.5 lift up front, main concern was clearing uca but I don’t want to create a cab mount rub problem

 

701 method bead grips - 4.5BS / 0 offset accordingly to their site. So that puts me at 3.5 BS with the spacer (I think).

I also have DK boxed UCAs with 315/75/16s - I needed the spacer to clear the UCA. Since then I have also added BTF LCAs that push the LBJ forward so I don't hit the rear fenders and some top hat spacers that limit front up travel to avoid the top. So right now everything clears and at some point I'll knock out more of the fender to remove the top spacers.
