I have seen a couple of these hanging around at local events and haven't had the time to ask questions. I know that j's racing makes one, but are there any more around??

 

I recently just install a Stable Energies guide bar for my camera along with an IO port camera mount and while expensive, it works very well. The video is stable and I do not have to worry about it coming loose should the unexpected happen.

Link OR go to http://www.ioportracing.com

 

the stable energies bar is the best bang for buck at 99$ for powder coated chrome moly steel, the IO Port mount is actually made by Bogen and instead of paying 100$ for it at io port, buy it here for 47$: http://www.bhphotovideo.com/pr...G/408

the superclamp works awesome, allows you to attach the camera on the fly to the bar or to any other object. I use it every autocross and have no problems with it rotating or vibrations. I used it last weekend at EVO Driving school all day during 40 runs and it still didnt move.
