That's some good advice B, thanks.
I did most of what you suggested. Before I drove down there I took out my sub and cardboard cover thing that goes on top of the spare.
I took the spare, jack, and floormats out once I got down there.
The track walk I could have focused more on the little things like you mentioned. I walked it with an two different experienced drivers, one was kinda talking to himself about ways to drive around the course so I listened in lol. The other was the guy my friend rode with, so he had a few pointers.
The first run I made, I had an instructor ride along with me, I ran about 80% but the one slalom I drove in a little too deep towards the end and tried braking and turning, didn't work too well, spun out lol. The instructor told me I did a really good job for my first time though, I had good levels of aggression and other than the spin I did well.
I got to ride with the instructor between my first and second run. He was driving an older Porsche 911, it was a cool experience. Obviously the run didn't apply to the way I would drive the course since it's a completely different car. But it was still interesting to see how a better driver handled the course.
The second run was pretty similar to the first. I made it a few sections past where I spun and the made the same dumb mistake in a slalom section a little faster than the first one I spun in.
The third run I ran about 80%, the places I had spun previously I took probably a little slower than I should have, but I wanted to avoid spinning.
