BBK cross drilled rotors squeaking?

My shop told me the tend to make some noise. I didn't notice any until recently, I rolled down my windows because of the nice weather and they squeak a little. More high pitch than other squeals. It's not bad, but I can see how it may be embarrassing for such a big brake kit to make unnecessary noise.

Hey Sean - A couple of years ago I installed drilled and slotted rotors and kept the original calipers. They squeaked like crazy at first but in a few months became just as quiet as OEM. This year I completely replaced my brakes with a BBK and now a slight squeak is back. I am hoping it will eventually go away like before.

Isn't that exhaust I sold you last year louder than any brake squeak?
