Now I see why you PMed me Jeff

My rig with the 235/85 x 16 is a "Widebody" gen 1. But interestingly I only run an "enhanced" 3" Calmini kit and ZERO body lift.
I have been looking really hard at my GV and I beleive I can get 235's under it without a body lift or cutting the rear of the front guards.
Part of the formula is the rim off set, but GV's do not have steering stops to adjust

Do not fear though, I will work it all out.
Years ago I fitted 31's under a 2" lifted SJ 413 without rubbing - once again wheel off set was the key. And they said it couldn't be done LOL

Think out side the square and you will acheive your goal Jeff. My advice, read a few of these threads and sit down and create something that has not been done yet.
Hint: Read up on and understand suspension geometry fully ( especially the McPherson Strut set up that our GV's run up front ). If you get a handle on ALL the variables then you will have the potential to create a masterpiece. Do not get hung up on the Castor setting though, if you run more than stock all that will happen is your rig will have a much bigger tendancy to track straight at speed. It is unlikely you will notice any difference at slow speeds. Camber - not actually that critical, but aim for around 0* or slightly negative. Toe setting - aim for 2-6mm toe in. I usually aim for the maximum factory setting with larger than stock tyres.
Of interest - My "Widebody" runs more Castor stock than a 1600 Kick. 1600 - 1*30' , 2000 V6 - 2*00' ( I mention this because I am trying to drop you a hint - read between the lines

)
Ummmmmmmmmmm - I have said enough

Good luck and let us all know how you get on
