the list of good forums or sites for various racing games.
Here is my list, starting with some older games:
Need For Speed 4 - High Stakes
http://www.racesimcentral.net/
In the forum section, you'll find a link to the High Stakes
Expansion Pack, which includes new cars and track, a manager
to deal with the cars and tracks, and an online chat and
TCP/IP race manager (IPLounge) which uses the car/track
manager to automatically select a set of cars and tracks
to use when joining a TCP/IP server for a series of races.
Also Mercedes Benz World Racing, Toca Race Driver 2,
Need for Speed 6 - Hot Pursuit 2, and other games.
Need For Speed 5 - Porsche Unleashed
http://www.racesimcentral.net/
There's a similar chat and TCP/IP race manager (the same
IPLounge) for NFS5. Several other games there as well.
Lots of downloads for various games:
