I am wondering if the GM Performance rotors rust up as fast as the stock rotors. My stock rotors look bad and get rust on the braking surface overnight. It is so loud when I back out of the garage in the morning I am afraid it will wake up the neighbors! Not a big deal, but irritating.

bumb i want to know also

 

Mine rust alot too. I discovered the MAIN cause of this happening was because I was washing my car (and consequently, my tires) too much.
It's a new car...I ...have issues with keeping it clean...
Don't know if you're doing it too, but if you are washing alot, don't spray the tires with water, clean them by hand. It seemed to help me.
But then again I live in a dry part of the country.

 

From what i've seen as far as eliminating rotor rust, you cant get rid of it entirely. What you are dealing with is oxydation of bare metal changing temprature rapidly in a moist envrionment. If you parked in a temprarure controled garage you would almost never notice that happening, though not many of us can accomplish that.

So...things you can do to slow it down
Don't spray your wheels/brakes after driving, wash them when they are cold.
Dont use cleaners like Brake Dust Buster or "Simple Green"
Try to park in a garage (only took me 2 weeks to throw all the junk out to get mine in)

However there are rotors out there that are coated to prevent rust on the hubs and outer areas that are not touched by the pads; such as Powerstop Cryo-treated Rotors.
These would reduce overall rust, but not prevent it on the surface itself.

 

So the Question still remains, are the GMPP rotors ZINC coated or not? I would buy them in a second if they are!

LMAO wtf!
