Sounds like some good footage. Defiantly looking forward to more of your posting. I was hoping to get a few passes with mine but my nearest track is about a hour and half away and it is starting to get a little cold in my area. I did get a line lock put in this past summer though so that will make life a little easier.
Whenever i go to the track that is all i see GoPros on the cars. It is really nice to see a slightly more POV version of things.
Is that yours at about 3:55 then? I kept looking at the headlights and nose thought they looked a little RX7 like and it sounded a bit throaty like my car way to low of a sound for a Rotor motor.
Also nice to see someone else who records as often as possible.
