it's from my old e36 front with 320mm disc (if I remember correctly)
discs are pretty worn for fitment guide only. planned for my ex-e46 project but didnt happen.
certainly come with its brembo braket which direct bolt on to my non-m e36, but not sure for e46, so please do your research
the calibre are in black with the usual white brembo logo/sign
let me know if I missed any info you after
not sure what it's worth these day, make me an offer if interested
