Just a thought, but who's installing the pads/rotors. Improperly installed pads could create uneven wear on the rotors and get them out of balance. I still find it VERY hard to believe you are getting enough heat in your rotors during daily driving to actually warp them. I can't even do that on the track or autocross when my brakes are being used HEAVILY. Do you live in mountains or drag the brakes a bunch?
