All I know is that when I ran at Commerce, I was running really slow times because, aside from my car I was running at the time being mostly stock, the end of the quarter is not well lit, and the actual end line is not marked. My dad came with me to watch me run, and the first run I did, when I came back he was saying I started breaking about 100' before the end of the quarter. Between it being dark and me being inexperienced it freaked me out, shooting off into the dark lol. I've never run a car fast enough to really gripe about stuff out of the box, but I know at the end it's bumpy as hell, which in a FWD car can be hell, and you see nothing and then all of a sudden you see a wall. Those are my main "gripes" with them. I've also heard about a lot of people wrecking there, and I can see where after they do Southern Nationals or another big event, the track is a mess (went to a fast friday event right after Southern Nationals and the trap was a mess).
