OS X Decent Racing Games?

[i7980X]

Hi guys!
I'm looking for decent racing games, worth playing.
I've been playing DiRT2, GRID, DRIVER:SF, Toca 3 for a while.
Those all are pretty good game, except DRIVER! no support for gamepad 😡

I prefer playing games in native for without wrapper.

I'd say F1 2012 but I do not think which is going to satisfy you.
