FYI, back when Joe was working on that brake setup, I did a layout to see if a similar setup would fit in my 17" rims. Minimum wheel barrel measurement I got was 15.5".
Note that it was just a preliminary layout, the caliper was just a sketch off an image. So it could be off. And this is worst case, could be that at the narrowest point in the barrel of the wheel the caliper is actually smaller than the above images makes it look.
