Focus brakes require a minimum of 15" wheel.
This is my suggestion also though just with different informantion. Find a spare set of stock Focus 15" wheels and throw some 24.5x8 slicks on them. Use a small spacer to clear the struts and drive on. The stock axles and dif are pretty strong for stock. I know, I've pushed mine beyond my expectations and they haven't given way yet (knocks on wood).
