I don't have personal experience with EBC rotors, EBC brake pads HH brake pads have worked well for me. I have used the same Chinese rotors since 2009 and I have not experienced any rusting issues and have used the EBC HH pads the whole time. I also have 6 pot calipers. Here's a 2015 pic:
My Brembo full floating 320 mmdiscs does rusts, because they are made or iron, better braking power than inox steel discs.. So there is no issue with this.
