Don't waste your money on slotted or drilled, there is not performance increase.
Search this forum and you will see a ton of threads on the subject.
Buy yourself a good quality aftermarket blank and some quality pads and your braking performance will be fine.
Many people here like Brembo rotors and they are good, I think they are a bit overpriced. I prefer Raybestos PG plus series.
If you really want to spend the money and get "better rotors", get rotors that are cryogenically treated
