Best gopro mount locations for track days?

A friend and I are going to jenningsGP this sunday and between the two of us we have 3 cameras. What's the best location to be mounting them so we can review and learn from our footage? via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/8jum31/best_gopro_mount_locations_for_track_days/?utm_source=ifttt
