I just bought my Scat Pack a few weeks ago with 26K mi and I believe it has the OEM rotors. I noticed they have rusted around the hub area where they're painted grey. They have also started to squeak (possibly due to glazing) so I am going to replace them with Powerstop Z26 rotors and pads. Should I be concerned with these rusting as well? I'm considering painting them but I'd prefer not having to do so. Thanks for any feedback!
