My GF use to have BMWs (new Civic now!) and bought these brake rotors, but they were never put on. She doesn't remember which BMW she purchased them for (she had a couple different 3 series models). They appear to be in perfect condition, and I assume are decent quality as they're made in Germany (as stamped on the edge of the rotor and printed on the box). They've been store flat indoors as long I have known her.
Hopefully the part number helps, the box says it's for the rear for E36 or E46 generations. I can't guarantee that, but if you have any questions, please let me know.
I'm located in Chicago and local pickup would be awesome, shipping probably isn't cheap, but buyer pays shipping. I'd like to get $50 + shipping. https://plus.google.com/photos/117144669358848523171/albums/6038222402230615665
