Nice, are you using the facetracking or some LED device? I tried facetracking a while back but it's a bit dark where I race so it didn't work too well so I built me a 3 LED cap to use instead, it works very well with the PS3 cam. Not using it much though, it needs a fair bit of tinkering to get the rates/translations right so it feels natural, otherwise it just detracts from the driving and makes it harder.
How do you find it so far? Good?
