Seriously, it's been killing me to not respond to you about this stuff prior to race program announcement. :lol
The rules for GTE were crafted with Ford at the table. Everything about the construction of the Ford GT has been based on the new homologation rules for GTE, which Ford was integral in lobbying to get x,y,z for (as all manufacturers do). The ACO is happy to oblige, as a Ford GT on the grid is a major, major win for them.
