Racing/simulator game

I once bought the game, but sold it because I didn't have any sort of controller or wheel back then, and playing on keyboard was pretty much impossible, so I sold it.

I believe it's free now, since they at least give download for "full installer" on their website.
However, I haven't tried that installer so I don't know is it really the full game, or not...
Worth checking out though.
