Drilled rotors give up surface area. Surface area stops your car. Give up that idea.
This is why I said don't bother with them if you're loking for better stopping power. I guess it would be worth it if you got better calipers and larger rotors. They don't decrease your stopping power too much, though. So don't think that you're brakes will suck if you throw them on.
For DD cars, it'* a visual only mod.
