neither slotted nor drilled give better performance than the flat rotors you put on. Braking is all about surface area and heat dissipation. The space between the front side of the rotor and the inside of the rotor, with the vanes, allows the heat to be removed quickly and efficiently, as the rotor turns. The flat non-drilled surface provides maximum surface area for pad work and stopping power. Many argue that slotted or drilled rotor surfaces are necessary to release gases that build up as a result of the friction on the pad on the surface. That is a myth. They are really just for show. Some race cars use drilled simply as a weight saving device, but those folks understand that there is a performance trade off, and they consciously accept that. The rotors you put on are the best for performance.
