Question on DBA T3 rotors. Installed them a week ago and it's been fine, but I've noticed some pretty serious discoloration all of a sudden today. Might be surface rust, not sure yet. But man...it's pretty bad. I drive the car daily, and took it to work and back. Pulled the wheels off to start my JR Oil Cooler install and saw this. Seems odd. This is with the OEM pads, I keep the Carbotechs for track only. These babies were super bright and shiny yesterday.
Your thoughts?
I'll get better photos with my DSLR if necessary. Thanks!
