Parts are available through your dealer or for the best price - getbmwparts.com
I'm really happy with my pieces - fits great and looks good!
They are 1x1 I have them, and they match the roof.
Best part about it is these are actually carbon fiber. not like all the aftermarket crap which is just fiberglass with a cf piece wrapped over the top of it.
