Exactly. As long as you are capable of engaging ABS then you are using 100% of the tire's ability to slow the car. The only way to reduce stopping distances is to increase overall grip. What a BBK gives you is increased thermal capacity which increases the car's resistance to brake fade, not shorten your braking distance; however, on the street I'd hope you're not making "10 repeated stops from 100 to 30 mph" because that would be pretty reckless and should be saved for the track.

If you want a firmer pedal and improved braking feel then get SS brake lines, better brake fluid and a street-performance brake pad but don't waste your money on a BBK unless you plan on tracking your car.
