Heck,
That was my first Auto-X and I was happy with 43.0xx and 43.1xx on SP5000 All Season tires.
Unfortunately, I never actually got to drive hard. My first run, I was just trying to drive the course.
I DNF'ed my 2nd and 3rd run. (Dunno how you do that after getting through the first time?)
So my fourth run was also a 'get through the course' run.
But I did have some fun

Let's see those results.
TB
