Wow, there's a lot of archaic information contained in this thread. I'll add to the pile.
You don't need slotted or cross-drilled rotors.
Conventional wisdom on cross-drilled rotors is that the holes allow for more heat dissipation at the expense of rotor strength--you'll crack the rotors. oh no!
It takes heat to crack rotors. If you have rotors that are properly-sized for your application, you're not likely to crack them. On the street, you're unlikely to crack a rotor on a Porsche/Boxster--they've given us some extremely beefy rotors, all things considered! Track is another story, which is why you don't see them in use, especially when you get used to seeing rotors glowing red.
Slotted offers similar benefits, but also does scrape the pad surface. On a street car, you'll see little to no benefit as the type of pads used aren't the type that will glaze over that easily. You also don't have rotors that are glowing red.
People like to talk about how both cross-drilled and slotted rotors allow for out-gassing of the pads. That's an anachronism, since the material used in modern brake pads does not gas out like that.
So, my point is, unless you're racing, you really don't have anything to do to the brakes. Get stock rotors, cross-drilled or not, and maybe play with different brake pads, but other than that, it's all just so much internet-speak.
That's what's happening if you ever hit the brakes and they suddenly start to flutter and let go.
