Need some good wallpapers? I did some looking around and found exactly what I was looking for here. The best ones are the last few events…

Now I need to find the same for F1…
I don’t know where to get those other than the official website http://www.formula1.com/
And for you SuperGT fans, http://supergt.net/en/ always has good pictures 
Yeah, the official F1 site has small pics unfortunately…
For the Subaru fans:
Has all sorts of good pics, but I can’t seem to find the larger ones. I thought for sure they are there somewhere…
Nice WRC link, the F1 official website blows. Their coverage is almost as bad as their management.
Check out www.rallycars.com . Lots of pictures there and lots of tech on rally cars of all eras too.
