Some facts and figures needed, please help if you can ;)

[mindgam3]

OK, as part of a project i need to find out the following:

Recent (2003/4) F1, WRC and NASCAR audience figures for actual spectators at the race and TV audiences

Plus general information on the rules and type of car NASCAR runs. Eg. the chassis, engine stats, speeds etc etc

Any links to the following would be very much appreciated

Thanks in advanced
