For those of you that are into sim racing on PC, check out Assetto Corsa. I picked it up this weekend for $20 from Steam (not sure if it is still on sale). The physics/tire modelling is really fantastic, especially for the non-race cars in the game. It's the most natural/intuitive physics I think I've ever used (my comparisons are iRacing and Gran Turismo). Track and car selection is small at the moment, but it's still in Beta. There is a modding community that is addressing the track/car situation. For example, I was already able to add the Nordschleife. I also saw that a mod team has both a street version NA and a Spec Miata in the works (goregous looking models by the way).

Highly recommend this for those interested in doing hot laps for practice between actual track days etc.
