big brakes, why not the 2012 Stang GT
once the brakes are strong enough to lock the wheels, the only thing that affects stopping distance is the quality of the rubber ;)
so a car with 10" or 11" or 40" rotors they will all stop the same distance depending on the tires
so the real thing you should remember is that if going bigger rotors means you have to use narrower wheels that's a bad idea.
