Yo I juz made a return to the site!!! It's been a while cause nothing looks the same anymore!!!!LOL!!!
Anyways..........Like westanbro stated I have the 5 lug conversion on my Zoo.
Question 1-------I was running a 18x8 all the way around with my old wheels BMW Euro wheel(Rims For Sale)
I think the offset was 50 i think(I'll have to check on that)center Bore?
Question 2-------rear axle basically is the yota axle,however it is narrower than the Isuzu axle, So I ran some
adapters(wheel spacers) to get my wheels to sit flush in the rear. For the Spindles I am
currently running drop spindles, But i will be changing that on my rebuild. U can lay the front
with a bodydrop without drop spindles(u get more lift also)
Question 3------Not sure on the big brake upgrade, but u will have to put some washers on the front calipers
to work with the yota rotors.
Lowzone pretty sure u remember what my zoo looked like with my BMW wheels but here's a pic. I will sell juz the wheels if your interested in um they're in great shape juz collecting dust at the moment!!!! LOL!!! Hope i helped u out with the info.
