I will to make a suggestion about the suspensions sounds. Y wish to hear, when you get on the inner border of a corner, the sound of the suspension making a kind of "prrrrrrr". You can hear the sound of the gras under the car, or the sand also, but you can't hear the noise of the wheels bumping on the white/red part (I don't know how do you call it).
Great game anyway.
