I think the mirrors are going to be useless on video, they are adjusted for the driver, not the camera, the passenger mirror shows the side of the car. I would try a video that frames the entire width of windscreen (no more no less). I am not super familiar with sebring but most racetrack corners are surprisingly "not tight". I just looked for videos and found this of a mini cooper s at sebring, his camera is tighter the windscreen width and only a few corners get cut off. Overall I think the larger viewing area (zoomed in) is worth a few apexes being lost.
