Get the drilled the slotted are not recommended for daily driving. The slotted take a layer of the brake pad off everytime you use the brakes to keep from getting the film on them.

No offense to anyone above but slotted rotors are always recommended over drilled ones. Cross Drilled rotors are only for show if used for regular street driving. Normal driving or even spirited driving never ever make the rotors hot enough so they can benefit from the cross drilled holes.
To top it of cross drilled rotors are always prone to crack or warp under regular street use. Dosen't matter brembo or autowerke floating rotors.
On the other hand slotted rotors are always better, because they are more solid, and thats why don't easily warp or crack. Slotted rotors also provide even brake pad wear and perfect stoping every time. Yeah, they might eat brake pad little more than the regular or crossdrilled ones under heavy spirited driving. On normal use no one is gonna notice the difference that much. Plus, what is better, little less life for the pads combined with perfect balance braking with security or show off rotors with holes, which are prone to warp or crack more than ever and have not much use in daily driving.
PS: majority of the high performence cars use (ultimate) cross drilled/slotted rotors and thats why the factory dosen't mind them.
They don't just eat up a little bit more of the pads, they eat a lot more. Cropssdrilled are not really that usefuul as sniper said, and that we really do not even need the holes because we don't run out car hard adn brake hard, often, and consistently as do track cars. Slotted are better, but will eat away at your pads. And i have not heard from anyone saying that their cross drilled rotors warped without them mentioning they race it hard and often.

There's nothing wrong with buying something that adds a bit of beauty to your car. It doesn't mean you're a show-off.
Porsche uses top of the line brake technology. They use cross drilled and slotted rottors. Not just cross drilled. I am not in the mude to argue, but the whole net is filled with people who had bad experience with cross drilled rotors when not used properly. Specially when cross drilled is combined with average brake pads.
Plus, I agree with the beauty part, but cross drilled dosen't add beauty, but reflects showing off just as riceness unless you are really a H4RC0R3! and use it.
right from tire rack:
NOTE: Brembo Sport drilled brake rotors are not recommended by The Tire Rack for track use or intended to be used in conjunction with race compound brake pads on the street. For severe duty brake demands see Brembo Sport slotted brake rotors.
I see no "riceness" in crossdrilled rotors. I think that's ludacris.
Also, I beleive if you're transplanting performance rotors in your car than you will most likely use performance brake pads. It seems a valid combination does it not? I know I personally wouldn't replace the rotors without replacing the pads. If anything the pads would come first.
I am not arguing that cross-drilled are better, but I am arguing that there's no "riceness" in using them.
