Very pleased to see this:

STL #3602

Replace 9.1.4.3.E.1 in its entirety with the following: “OEM brake systems must be used. 1 or 2 piece ferrous rotors
that do not exceed 290mm in diameter and 28mm in thickness are permitted. The standard production calipers or any
4-piston calipers are permitted.”

I do need some clarification,

"OEM brake systems must be used" but "The standard production calipers or any 4-piston calipers are permitted.”

So I can use aftermarket calipers that are not oem?
