Still pondering the brake up-grades to fit the rim cavity and accommodate the increased rotating mass. From what I have read in the FTE, the F-550 has an axle adapter plate to mount the calipers to what otherwise is an F-350 axle. Then still need to find a rotor that has the 8x6.5" bolt pattern, for as I understand it these axles are 8x170mm bolt pattern.
