Pretty sure you need an 18" wheel with Z51 brakes. It has nothing to do with to with your subframe. You might get away with base C5 brakes. Tobin has the fit templates for both on his Kore3 website.

Well I'm also wondering if a bigger rim can fit up front with a 255 tire. Also the reason I wonder about the back spacing is the wheel fits up to the bump in the hoop. If that was further in it might work.
