ive been playing grid 2, and i may have missed the explanation of them, but i cant figure out what they are for apart from getting very small amounts of fans. im using the ps3 version so yeah.

Nope, the fans are really it. They show off race modes that you usualy don't see in the seasons, and you get fans.

^That, and depending on what season you're in, they let you test-drive cars that you haven't unlocked yet.
