Hi there. I've been noticing that the forum isn't quite active anymore. If you haven't already, join the facebook group "iM Enthusiasts" and any questions asked should be answered quicker there than here.
For my two cents to your question, OEM for me is a little too pricey lol. I haven't had to change my rotors yet, but I hear the Powerstop Evolution Geomet Coated Kit or the Powerstop Z23 Evolution Sport Brake Upgrade Kit on Rockauto are good. I did change my brake pads about a year ago though. KFE ceramic brake pads off Amazon. No problems at all. Will change rotors on next brake pad change though.
