It's about weight, or more specifically momentum. Adding power does increase momentum, but only if you use the right foot. A 3000 lb. car with X brake setup will stop in X feet from X Speed. If that same car gets a more powerful engine, it will get to X speed faster than before, but the rest of the variables remain the same.

If tracking the car, where the brakes are applied more fully, and frequently, the larger brakes are an improvement because they shed heat faster and so don't fade as soon. But on the street, where's there's rarely seconds between brake applications, enough time exists between braking for the brakes to cool and not fade.

Don't forget, the difference in stopping distance between the 'S' brakes and Base brakes is only 4' @ 60MPH. Could that 4' make the difference in some rare circumstance? Of course. But that's an endless debate, what if the needed improvement was 5'? Than neither brake setup would have an advantage over the other (for street).
