I used the Zimmerman brand cross drilled, and they make a lot of noise. I went back to standard Brembo. Besides, they aren't really an upgrade b/c they are the same size rotor with 15% of the surface area drilled out. Physics dictates that less friction will lead to less stopping power. The schtick is that they cool better to prevent warping; next time you are on the race track be sure to keep that in mind. They have become one of those aesthetic things. I've seen slotted rotors for C900's, but I haven't heard about a noise problem with them. If you want to upgrade your brakes, I hear switching to 9000 calipers increases performance.
