Racecar Rollbar Mount for Camera

[siemi]

I'm just looking at putting a camera mount into my Racecar. I was just wondering if anyone had experience doing this and could recommend a good rollbar mount. I have a DSLR (Canon 550D) and was considering using this as it has good video quality. I have looked around and haven't seen any information on people using DSLR's in race cars.

Thanks for the feedback.
