Any point of getting BBK for street use?

This is the kind of question I semi-know the answer to, but would like to get educated further on M3POST.

I am contemplating on getting a 4 pot / 4 pot BBK for my car. The ricer in me thinks that stock brakes are a bit plain and weak in comparision for the rest of the car.

Then there's performance, which is where my question lies in. I am looking for these, in the order listed:

- Strong initial bite
- Low noise
- Low dust

My understanding is that BBKs are primarily designed for track use, as more pistons = quicker heat dispense. In other words, more pistons does NOT necessarily translates to shorter stopping distance. What DOES result in shorter braking distance are larger rotors + calipers (and hence pads?).

So in theory, by getting a BBK with larger diameter rotors, I should be able to achieve stronger braking, on street or track?

Also, what diameter would still fit in stock 220M's? My budget is limited, and doesn't allow me to get larger wheels.
