I like this confusing discussion, but I agree with JIM.... It doesn't matter how much HP your car has. HP doesn't impact brakes. As it was once explained to me, as long as you have enough braking power to "lock them up" then you have "enough brake".
The advantage to larger brakes is their ability to stand up to REPEATED heavy braking. Heat management. Stopping once or twice on the street, or slowing from 70-30 a couple times on the highway will not show much difference.
BTW, the reported 7 foot difference is braking distances is likely MORE attributable to weather, tire and road conditions than the brakes themselves.
