Well, given this is a 986 forum and this is the boxster racing sub-forum, I feel bad that I don't (yet) have any track videos in my 2000 Boxster S race car project car, but heading to the track next Monday with it so should have some to share then.
In the meantime, here are a couple of videos in my other track car (2015 GT3):
2015 GT3 at Laguna Seca, PB run on fresh tires & no traffic (rare occasion!):

2015 GT3 at Thunderhill 3-Mile, had some major problems with auto-focus on the phone I was using. This was before I installed the proper dual-camera VBOX system seen in the WRLS video above.

The Thunderhill video is old, and I was recently there again for the first time in over a year. I was able to match the previous PB on the first session and was perfect conditions to go out and lay down a new PB (hoping for sub 2:00) but I blew a coolant line that ended the day for me
Car is all fixed up now, but that was a write-off of a day
