I did a search on the forums before posting and didn't find the link to this video anywhere, so I hope it's not a repost. I don't know how long I have this video on my harddrive, but just this week I thought: "TestA.mpg?! What's that?" After watching it I did recognise it and thought to myself, that this is a very good video and that you all should see it.
It's an onboard video of an F355 tracking on Watkins Glen at an FCA event. There are also a 333SP, 360 (GT or Challenge car) and F40 (LM?) on track.
There's music in the video, but it's not bad. You can still hear the engine(s). I quite like it actually and it serves a purpose as well: to drown out the wind noise.

Enjoy!
