Since changing to Hawk Ceramic pads from OEM on my M, I now have vibration through the pedal as the OP stated(not like a warped rotor feels, just vibration at certain speeds). I also noticed this when I put cross drilled rotors on a 944 I had years ago. I suspect what is going on is the drilled rotors are noisy compared to the OEM rotors he had previously. It is likely normal or could be pad related.
