AnotherS197GT
Serial Valve Dropper
Got a chance to test this over the weekend. I know some people have been curious about this, but it turns out they bolt right up! Using the same bolts as the S197. This is with an S197 GT500 rotor, not sure if they are the same as the S550 4P rotors or not. You will need a different brake line, since the OEM S197 lines will not work. You should be able to use a 6P line from a 13/14 GT500.
