i've got a lightning and it's got stock brakes in the front with wilwood rear brakes. both front and rear have 5/8ths studs pressed in. the wilwoods sqeak like crazy but it's not something i can't fix when i get time. stops the truck ok. the stock ford lightning brakes would cost a bundle from ford i would imagine. wilwood has several different ways to go and i'm sure brembo does as well. let us know what you decide on.
The Lightning has a different spindle and brakes, so you would have to change spindles also.
