I have for sale a brand new Vis Racing rear bumper (also called M-Tech or Mtech) for a BMW E92 335i Coupe. It does have the divots for PDC Mine was an 09 but I believe this fits years 07-10. I didn't end up needing it in the end because I got the OEM one fixed but paid over $500 shipped for this. It's fiberglass/unpainted and includes the rear black diffuser also. Great mix between stock and aftermarket clean look. Pickup local here in Denver. Email for additional questions. Thanks!
