As far as I know all deals with real life companies weren't initiated by the devs. It was always either the company approaching the devs by itself, or a community member starting the relation.
So if you think the track is worth it (I'm a bit critical), then write them, introduce them to LFS and tell them that they'll get loads of free advertisment if they give the LFS devs the rights to make the track, or even some of the GPS-data of the track if they want to speed up the process.
It looks a bit like this track wants advertisment, and it looks as if they definitely have extensive digital data of the track available. Looks like a well planned track.
The Ascari KZ1 doesn't look bad either. Someone throw those peoples the link to liveforspeed.net please!
