Rich, the Camaros were there testing for the ARCA/SCCA race events planned for that weekend. Yeah, they were fast...good motivation, but wish we could have hung a bit closer to them!
Karen, we took your lead last year and went with RacePak G2X. We maxed out the optional sensor ports with Water Temp, Oil Temp, Oil Pressure, Fuel Pressure, and R/L wideband O2 sensors. Has worked great for us and the real time support from RacePak has been helpful with any issues we have had with calibration, setup.
The cameras are made by Contour...records up to 1080P (which does require a pretty powerful computer to view/edit) and the latest version has 170 degree wide angle lens (in #56), while my older version is 135 degree. They had some problems with the earlier versions but were good with warranty and Craig's newest one seems fine and runs about $200, plus another $50 or so for bigger memory card and mounting hardware. We're using the suction cup mount off the back of the car. Contour | Products | Contour Roam
The magic of pulling it all together is Craig staying up all night to get everything synchronized! Not sure where he got the dashboard used on these videos (maybe John George?) but I am pretty sure he's using Nero to do the video synch.
