For sale is new, authentic Vorsteiner Carbon Fiber Rear Diffuser for an E92 M3. It has NEVER been fitted or tested on a car and has Vorsteiner's yellow Achtung (warning) sticker still on it. The MSRP for the diffuser is $1,283.00. I am asking $900, but am open to reasonable offers. It has a small blemish on the right hand side but very unnoticeable. There is a picture below.
Please feel free to to pm me if you have any questions or concerns.
