New to sim racing

Hi guys, I am pretty new to sim racing and very new to RF2 ( Just bought it in the steam sale ).

Now I seem to be missing a hell of a lot of content, which I am guessing has something to do with the game switching over to DX11?

Question is how do I get the tracks/cars that come with the title that I am missing?

Any help on this would be very much appreciated.
