As for the holes, the ECS GEOMET rotors are a machined rotors. The holes are not cast in the rotors.
I LOVE my pads that came on my '11 335 (as compared to my '08 328) my n55 e92 pads produce virtually NO dust. What pads should I get to replace my current pads to get the same "no dust" performance? I do plan to track my car, but 90% driver (FBO).
