Thanks for the links, PapaK !! Greatly appreciated!

That Ford GT competed at Sebring this year, I think in GT2, or perhaps GT1. Might be neat to add that to a home-brewed ALMS series, along with the DBR9.
The DTM mod sure looks a lot like the one for rFactor, so I am wondering if it's a port. That one is also pretty fun, although the graphics weren't up to the standards of some other rF mods. But the cars are fun to drive.
What I really like the looks of is the SCC v2.38 mod. I recently read a book about the development and history of the Porsche 956/962, and so I am pretty interested in that era of Prototype racing right now.
