SSBC Stainless Steel Brake Company was suggested as a supplier for a larger bolt on braking solution. They have an 8 piston, 4 per side, stainless steel sleeved caliper and rotor kit. I can't tell if they are larger diameter rotors though in the provided information. I'll give then a call tomorrow before 5 eastern.
The F450 front axle has that extended hub then reverse wheels to match the dually rear offset I presume so the front rear and spare are all interchangeable. It may be as simple as getting the back plate and mounting hardware off the larger truck along with 19.5-inch rims and swapping them onto my front axle. More research needed.
