Kim,
Dominic and Cole bought a GoPro Camera last year, not the HD version but works really well. Wide angle with all kinds of different mounts..We put it on both of their dragsters using the roll bar mount, however, there tubes are only 1 1/2 and would not open enough to go on my chevelle. i used the suction cup to mount to the door glass. On my brothers car , we used the dash mount....here are some videos.........
in my car using the suction cup
in my brothers car on the dash
on the dragsters using the roll bar mount
mounting directly to the roll bar on the dragsters, the sound is distorted a little. in the directions it says to remove the rubber seal on the case to clear that up...we havent done that yet....hope this helps
