Just have to combine the right rotor ring with the right rotor hat and drill to our bolt pattern. Given how common 5X114.3 cars are might even be some off the shelf 1 peice rotors that work.

Edit: also makes it very easy for companies like Stoptech to offer an aftermarket kit since they wouldn't have to develop something new.

I can't speak to this directly, but Tom (YT) thought that the STI Brembo calipers were already paired with the largest rotor they can use properly. If you went to a larger one it wouldn't match the inner radius of the caliper properly and would have either pad hanging out past the rotor or the rotor hitting the caliper.
