Just picked up a ChaseCam triple suction cup mount for autocross, i would highly recommend this product if your looking for a camera mount for autocross. Two thumbs up

hears a little test video i put together, i only got two different views due to rain. O and yes i know my drifting skills suck, i am not a drifter
