Slotted rotors for street use are not necessary. The purpose of the slots is to allow gas to be expelled from under the pad, thus keeping the pad in contact with the rotor. Modern street pads don't produce much gas, if any, and the missing contact area of the slots outweighs the benefits of gas removal. You shouldn't ever be getting the brakes hot enough on the street to generate gas anway.
