Backspacing on Sport Trac

[Bannanatruck02]

Hey Guys,
I am toying with the idea of placing new tires/rims on my 2002 ST.... Here's what I have in mind:
1.2" TT in the front
2. 2"Warrior Product Shackles in the Rear
3. swapping my 16x7 for 15x8 and 32"ish tires.

Here are my questions/concerns/goals:
1. This will be a vehicle that will see mostly on road driving, but weekend 4wd (nothing way over the top)
2. What backspacing is common would be good for the aftermarket wheels? I've heard of 3.75 being used on the 15x7" rims on various rangers.
3. I would like to avoid "rubbing" issues.
4. How much stress would something like this place on bearings, hubs, u-joints, etc?

Im running a slight twist in the front, shackles in the rear, 32x11.5r15 all terrains on cragar soft 8s 15x8 4inch backspacing, very slight rubbing on lock to lock (more so when aired down) just haven't trimmed the inner wheel yet


Ive had 32 with a higher backspacing wheel (i thinka 3.25 ish) with not problems either, been running it for 4 years

Thanks a bunch, man! This really helps.. If I wanted virtually no rub, would this be possible? Would Is it possible to get backspacing higher than 4"? What about wheel spacers? Also, very nice Sport Trac that you got! Looks awesome with those cragars!!!
