AC Schnitzer makes an nice trunk lip spoiler for pre-CLI cars (2 models: coupe and cabrio) but it is not carbon fiber. Not cheap either. I had one on my ex-2005 645Ci and liked it a lot.
I think Vorsteiner makes a smaller trunk lip spoiler in CF (I've seen photos if older threads) but I don't know if it fits both pre-LCI and and LCI models. It might since it sits on top of the trunk (does not extend down to the 3rd brake light on LCI trunks). Is that the "VS" one you mentioned?
Just a thought, but you could buy whatever spoiler you like and then vinyl wrap it in "CF".
