Without tubbing it, you are limited. I had my rear built one inch shorter per side, and I am running 15x10 with 6.5" backspacing. You still need to keep the tire in the same limited amount of space when you're not going to tub it.

The 4.30 gear will probably be too steep unless you are running a lot of rpm through the traps. I'd go with 4.11 gears with a 28" tall tire. Bob
