Here is mine I used it for the Nurburgring this past sunday there was a little bit of shake but not that much for how fast iwas running on the track.

I'll post videos this week to show how it did

 

I have a "SPINMount" from Spin9k. It worked well and passed all tech inspections from NASA, PDA & MazdaDrivers.

I don't need it anymore. I will ship it to you for your cost. You will have to buy a "Ball Mount" to it ~$50 but it works...

SEARCH on SPINMount on the forum for pictures.

 

My next idea for this is the bullet cam they sell in the UK, I'm not worried about passing any tech inspections because they don't even inspect your car before you go on the track.
