If you want to know about real world racing, ask away. I race in the real world racing a 2 stroke Rotax DD2 Kart at the club level (it's my mini Formula car capable of pulling close to 3Gs in the sweepers). But if you want info on these F1 games as well as other racing games, a good place to go and seek information is:
