Doing some Assetto Corsa tonight at 8PM EDT. We'll driving some open wheel cars around Spa this time. Once enough people join, the server will switch to qualifying/race mode and we'll have a race or two. No DLC needed, mods are in the Mega link below.
Server is running the new mods now if you want to test your setup or get some practice in, let me know if you run into any issues.

Also, Assetto Corsa and all of the DLC is currently on sale on Steam if you're interested. Even if you already have the game, try to pick up [spoiler]or pirate[/spoiler] anything you're missing, because I'm probably going to start using more of the DLC cars/tracks soon.
