how wide and how tall ?
 

How wide and how tall can i go with a 15x8 wheels in the back. I hopeing for a 28x 10.5 or 11.5, I guess just give me some feedback and let me know if that is even a good wheel for that wide of a tire.

26 will fit no problem, 28 will take some work.

what kind of work?

bfh mod its not that bad

not just that, you will most likely need adjustble lower control arms and you will probly need to trim some of the rear portion of the fender. I'll attach a few pics of what i had to do on mine to get them to fit.
