The ones that will take the best beating often don't stop worth a damn until you get some heat in them. There is a noticeable performance difference with two piece rotors, but that's mostly just from reducing unsprung weight.

Also, brakes don't stop the car. Tires stop the car. If you want shorter stopping distances, get stickier rubber.
