Excellent report! That track looks like awesome fun with the elevation changes. I've seen the NASCAR race there plenty of times on TV and even driven the track a lot on my PC with the old NASCAR 2003 Papyrus racing sim.
But of course, nothing is like the real thing.
Your car looks great too - I'm close to ordering a 2018 Summit White 1LE, black bowties, and PDR myself - and if I do get it, the first mod would be the rock guards!
Good advice about the painter's tape too. Thanks for sharing the video and story.
