I purchased a set of your Centric standard rotors a few years ago from you. They were the cheapest ones you offered anyhow, definitely not the premium option. I used them for a full year of frequent HPDEs where they got abused, 2 seasons of autox, one in which I won that year in my class, 1 year of daily driving on them on top of all that. Those rotors have since sat collecting rust since the car was on jackstands for 2 years. I finally got the car started to where it moves on its own power, did a few good stops and those rotors are just as good again.

I measured them, still good on thickness, no excessive runout, no grooving or glazing wear. I never did really get rust on the hub surface until the car was sitting on jackstands either. I attribute the rusting more due to the climate out in the Midwest where the car was being stored though.
