In the attached picture I have a 2017 S550 6 piston caliper over a 14" 2012 GT500 rotor. The wheel is a 18"x10" Weld. Keep in mind, this is all mocked up on a '73-'76 A-body 10" drum brake kunckle. I have yet to get to a bracket design that would work on the disc brake knuckles.
It's tight in the wheel barrel and tight to the backside face of the wheel for sure. I would have to measure the clearnace as it's been a few years since I have messed with it.
I am going to pick up a 14.2" SRT front rotor to use for mockup. The SRT rotor will move the caliper back from the rear face of the wheel for more clearance. Not sure I can afford the extra .100" on the outside though.

I'm also wanting to work on fitting 2018 GT350 radial mount calipers in there too as they are also cost effective like the regular S550 6 piston Brembo.
