So i'd like to get some more websites covering racing. Anything good will do, but tech stuff would be the best. I know of Racecar Engineering, it's awesome but there could be a bit more updates. I'm also aware of Planet Le Mans. So some more sites would be useful. Something covering WTCC, rally (WRC), also looking at the tech side, if it exists.

Formula 1 - Live
http://en.f1-live.com/f1/en/index.shtml
Moto GP - Live
http://www.moto-live.com/motogp/en/
24h Le Mans - Live
http://www.racing-live.com/24hdumans/en/
WRC - Live
http://www.rally-live.com/en/index.shtml
Dakar - live

They are some really good sites with updated news all the time.

for WRC you don`t have to go very far - on the official website http://www.wrc.com/ you can play some interesting vids and read news. During WRC events, tune in to official World Rally Radio for live coverage of the rally http://www.wrc.com/jsp/index.jsp?lnk=320 (splits, interviews, music, fun)

"TVU-Player" has the american "SPEED" channel with coverage of NASCAR, DIRT OUTLAWS, American Les Mans, MotoGP, Formula1, Superbike...

www.autosport.com gets most of the racing covered... the news are usually free, the more technical stuff requires a subscription...

I agree with autosport.com. Besides F1 covers nicely all the other important series.

http://www.f1technical.net/ is a great website.
