Hi. I've long been playing car games and have since evolved from my keyboard-wielding NFSU arcade-physics days to seeking more realism. By realism I mean NFS Shift without any aids on and at the hardest setting, same with F1 2010. Obviously these games are not hardcore sim racers. And that's an avenue I want to explore next.

I've been hearing rFactor, GTR2, RBR, etc. as the dominant names in PC sim racing. I really want to try it out. How do you download the cars? If I'm not mistaken, these cars are just mods right, so they're not built in with the game?
