The aero kit installation guide has a part number for the black structured paint, but BMW parts shop has no record of it in their system. Anyone know what to do to get it to match the rest of the car on th bottom? Trying to get them an answer today! Thanks!

 

I am sure you moved on at this point. I went through this and finally found a match. It's called Organisol made by PPG. It's a near perfect match. It was originally made for Chrysler to use on trim panels, etc of classic Challengers and such.
