Updated GP3 tracks and carsets

We have many wonderful tracks for GP3 and perhaps a smaller update for some of them would be very nice. I thought about the Sebring 12h track, Jarama with the newest layout and Brno in a scandura-version (I know it is on its way ...)
Furthermore we don't have a 2007 Champcar carset as far as I know.
If someone could find time I think the above mentioned will make many GP3 gamers very happy... Please think about it
