From everything I have looked at there is NO brake caliper upgrade that clears the stock wheels without using spacers - the barrel of the wheel is one thing, it's the lack of spacing to the backside of the spokes.

I ended up getting 6piston calipers and 14" 2piece rotors through Reaper Brakes. I have had no issues with pedal feel/travel on this setup, nor have I heard of anyone else doing anything to the master cylinder when upgrading brakes.
