Wheel fitment question backspacing offset

A friend of mine had a 2013 Tacoma that he put 20x10 Fuel wheels on it with 33x12.50 tires on it. The lift he bought is +3" +2".

I want the same look on my 2009 but not sure what backspacing and offset his wheels were. I don't really want to cut cab but if needed I will. I just want the look. Both trucks are 2wd.


Anyways here are a couple of pics.

Any help would be greatly appreciated.

 

There are only two options the wheel comes in a 20x10 with 6x5.5 lug patter according to http://www.fueloffroad.com/specs.cfm?id=2579&name=D531.

-12 offset with 5 backspacing or -24 offset with 4.5 backspacing.
