It's possible to have ai driving with wind:
1. Add ais, start race
2. At start of race, type /wind (0 or 1 or 2). 0 is no wind, 1 is low wind and 2 is high wind.
3. Restart race, the ais should be driving with wind!
I found a blue one for fz5, closest I found http://img31.imageshack.us/img31/7625/fz5gt3rsblue.jpg
The Gt3 Rs skins I found for fzr were the older ones
If someone does the skin, is it possible that it could be added to the stock car skins list?
GT5 style - No, it will be all random as already stated.
Maybe a more "free" choice track maker will be better, then again there are more important stuff to implement
OH SH-
That is one amazingly lucky driver, did that remind me of Massa @ Hungary? (though the wood missed the driver rather than hit him in the head and crash)
