I made a few videos when I was working pit crew for Team Sahlen's at Roar Before the Rolex last weekend. One's a pit stop, one's a short walk through the garages where the DP cars are.
It's a practice session, so the pit stop isn't what you normally see at a race. They inspect things and adjust the shocks, but it's not a super-fast affair. They certainly did do fast race-style pit stops, but I only had time to capture one. This is it.

And I shot a video when I went for a brief walk through the garages. It's mostly DP cars, but there's a few RX-8s, BMWs, and maybe a Camaro in there as well. One of the DP cars has a complete rear subframe sitting out.

Maybe not the most compelling footage, but I figured somebody might get a kick out of it.
