Thank you guys for all the help

 

Lug nuts torque to 100 lb ft on clean and dry threads.
Did you break-in your brakes before high speed driving or heavy braking?

 

to the site!!! Not sure what's wrong but apparently something is.

to the forum and brake gently

 

Turn up the stereo, the noise wil go away.

 

the slots could be making the vibrating noise you are hearing. could be the newness..

 

along with the torqueing spec's and tightening the lugs in the "star" pattern, make sure you clean the mating surfaces of the hub and rim very well....use a wire brush on rust and dissimilar metal corrosion.....as per GM's TSB. Also, either remove or be extra careful with the retaining clips found on the hubs. They have been know to cause problems such as you discribe.

 

Is it funny good or funny bad?

I had cross-drilled rotors (front & back) on my last car and they often made a faint "wizzing" sound, especially when cold or wet. It was perfectly normal in my case, it was just the sound of the holes passing by the brake pads. There were no actual vibrations though.
