Mickey Thompson Classic 2 as the 16x8 is 3 5/8" backspacing.

Or an Allied Alloy
http://www.alliedwheel.com/one-piece/rockcrusher.html which is a rip off from the Weld Stone Crusher. The cool thing about these is that they have 3 5/8" backspacing and they are fairly cheap.
I know the Mickey Thompsons just got hammered for the finish corroding with road melt solvent.
The other option is custom steel. I've found these to be expensive and not very attractive. Getting a raw unpainted wheel doesn't appeal to me. And where I live we don't have powdercoaters on every corner, heck we don't even have a chromer in the state of Idaho.
It is tough finding less backspaced wheels to make it wider in 16x8. A 16x10 with 4" backspacing is fairly common. Which really widens you up but you would most likely need to be running wider tires to keep them seated properly fo the trail. Then you can be really wide!
On my 91 I ran 3.25" backspaced wheels 15x8s and I loved the added width. Technically, I was 4" wider than stock minus the added tire width just by switching wheels and tires on that rig.
3 5/8" is roughly 3.6" so I'd be almost 2" wider than stock than a stock FZJ80.
17" rims are much worse as most are 5" backspacing which means if you use a Sequoia 17x8 you are 1" narrower than stock.
I was really against spacers but I'm thinking about doing a 1.25" spacer on my 94 because I don't like the two wheel choices I've found with less backspacing. Plus they are cheaper than buying a new set of wheels. I'm still a little unsure of the safety thing. I want my wife to be safe in this rig and not have to worry about retorqing lugnuts.
I have 2" spacers with 3.5" backspaced 15x8s on my 40. It needs the width to clear the 36x13.50" Iroks. Technically I'm running a 1.5" backspaced rim which I don't think is possible to make.
It appears there are a lot more people running spacers than what I thought. I'm going to run without for awhile and see what I think I need for width before jumping on the bandwagon.
