My knowledge is limited, but aren't manufacturers seeming to fight a "biggest rotor is best" battle, especially on street cars, but more as a marketing ploy?
Without ABS, my understanding is that rigid calipers and lines should be important on a setup for good pedal feel. And cooling is better via open rotors with directional vanes and good access (ie ducts) to cool air. So a bit less than 12 inches isn't a big rotor by today's production car standards. But on a 2000-2200 pound car, shouldn't the basic RCR setup be more than adequate for hot laps at the track, probably full-on racing, and over the top for street use? These are much better brakes than on the originals, and the car is lighter.

Of course, I have not yet got the talent to threshold brake, so I am certainly no expert.
