Just get plain rotors, drilled or slotted are both unnecessary for street use and increase pad wear, drilled and slotted are particularly bad because the slots force the drill holes to be placed in improper places, causing uneven brake pad wear and shorter life. Also the holes reduce mass so you end up losing fade resistance. The old logic with holes and slots was to relieve surface gasses that came out of hot brake pads but brake pad material formulations have advanced a lot over the years and gassing is really not an issue anymore.
