This was my last session on Sunday. We ran the course in reverse with one small change...
I was leery of my tire wear and the car didn't quite feel right so I quit pretty early in the session after a few good clean hot laps. After the car sat in paddock for a while, I noticed the left rear going flat. Good thing I quit early and this finished my day.
Still haven't investigated what it picked up and don't really care...as all tires are shot now.
