Thought I would post up my options for mounting a Gopro without using a suction cup. I was told that in-cabin suction cup mounts were banned when I was doing a track day at Phillip Island, which was pretty frustrating as they were fine to use at the other tracks I have been too.
First option is with the camera offset to the headrest, using 25mm square section aluminium tube with a couple of u-bolts and wing nuts to attached the mount bar to the headrest poles. I have also drilled a couple more holes to potentially allow the mount to be swapped over to the driver's seat, with the camera sited further out from the headrest and getting an over-the-shoulder view.
Second option if the first option isn't deemed acceptable by the scrutineers (possibly due to perhaps a metal bar protruding out from the headrest? Not sure if it would be an issue but figured worth trying to cover all bases :tongueout
is similar but mounts the camera centrally in front of the headrest, which should give a 'passenger's eye' view and means that there isn't any metal bar protruding sideways towards the driver out from the headrest. The smaller piece of 25mm square section is fixed to the larger bar by the 1/4" bolt that passes through and threads into the Gopro mount on the front. Due to the fact that the headrest/seat might have a tendency for movement under heavy braking/cornering I've also used a small 20mm right angle bracket on the rear and located on the 1/4" bolt as an anchor point for a tether to the d-ring on the floor to ensure the headrest/seat is held down tight to restrict any movement (I'll put a similar anchor point on the first option as well).
Pretty quick and cheap to make. Hopefully between these and the suction cup mount I won't have any more issues with being unable to mount my Gopro in-cabin no matter where I go.
