If you even tell me any reason not to use drilled and slotted rotors i'll pretend you never exist. Myself and many others who run in the STU, and STM and SM classes will prove to you otherwise on a track.

Drilled is the worst thing ever. Slotted is fine.

Should take a gander at this:

I run 14" rotors and 4 pot calipers and still run solid rotors.

Probably nothing wrong with what you got, it will not last as long probably (but the way cars are traded out every 3 years who cares). There is no real gain to drilled, pads make more of a difference and what not. Avoiding China rotors is key too.
