I'm selling a painted E92 M3 Authentic Vorsteiner Type II Diffuser Painted Black. The diffuser has some imperfections from the painting process but they are not noticeable at all when mounted on the car. 3M tape used for mounting and buyer must buy new tape to mount. Seen these go for alot more on this forum but asking $400 so It can sell quick. PM with any questions. Below is the link from Vorsteiner. Thanks!
