Racing starts at 2 pm, you can go there and setup around 12 and check your cart out. I run a 12 64 gear in the heavy. The track is 10 miles outside of Mt Vernon on I64. It is a small but fast.
Yes, racing is at 2.
Hotlaps will probably start around 1ish. They do not do hotlaps by class....you just go out and hotlap after the track is ready. It works out well if you want to try adjusting on the kart. Just pull in and change whatever, then go back out.
