I am selling a used set of rare 21" I-Forged Essen wheels from a 2007 BMW M6 painted in a custom flat black with polished lips. These are special order hard to find sizes in 21x9.5 front with Falken FK-452 255/30ZR21 and 21x11 with Falken FK-452 295/25ZR21 rear. 3" front lip and 4" rear. Offsets not available. I assume they will fit a 645CI or 650I without issue. No visible curb rash. No TPMS included. One wheel is missing the center cap, so I replaced with a similar looking cap to prevent an eyesore. This setup was purchased in July 2010 with about 4-5k miles on the set. No flats, patches, plugs, or stories. I have included pictures of the wheels on and off the car. Sorry for the dark pics. Asking $4000 for the set. Email me at [email protected] for more details or any questions.
