Come to Europe, then the time zone is more of a help for you.
Last time I checked there were 125 servers with people on.
Well, nothing has changed on the last year, but some good servers have appeared between all the cruise, drift and demo servers. I'll take a minute telling you some of the servers in details.
For example we have FM servers, which usually offers great FOX / formula racing. The only problem with it is the people it attacts, but usually there are admins on the server that cleans the mess out.
Usually the races are in such a lenght it takes around 5+ minutes to completele them. Admins on this server is fair, maybe a little rough sometimes, but I guess that is needed when you trying to take controll over 32 mad people trying to win in turn 1
A other server we have is the AMR GTR (I think that is the name) server. Here it's Aston National with the GTR cars, and usually set up for 6 laps and a mandatory pit stop. Usually good fun, alltho the admins seems to be too picky on "you sweared, ban" , or "you using chase view, ban" and things like that, but at most times they are overcomeable
A server which offers the best TBO racing at the moment is the Ready 2 Roll server(s). The FXO needs restrictions on this server, which makes the races more close and great fun. The lenght are longer than the two other servers mention aboved. The server has a insim that let the race run for 10 minutes + one lap. That means that you drive as far as you can on 10 minutes, then when time runs out you have to cross start/finish and then one more lap. The admins here are really great, and I yet have to find anything wrong about them,
