I have a set of two brand new rear Brembo (27231) rotors and a set of two used rear OEM (05299393AA / 28175) rotors with 12,000 miles on them. These were for a gen3 car, but I understand they'll work on gen4 (not sure about gen5). I'm thinking $100 each for the new ones and $75 each for the used ones, if anyone is interested. I also still have the HRE wheels for sale that I posted here in 2014.
Ken, you should take them to the scrap yard you might get more money :P
