The rotors being cross drilled and slotted help a lot and the ss lines and updated pads with the blue racing fluid pretty much gives great stopping power for the street. Obviously, bigger rotors and calibers are ideal for max stopping power, but for street use, the stock 4 piston calibers and cross drilled/slotted rotors with racing fluid and ss lines are perfect. Hope this helps.
