Straight rail on Eriez dirt oval

Local Dirt Track opened up last year that is very close. Only 20 minutes instead of 2 hours away Sprint course. My kart is setup for the lefts and rights and I wanted to try Dirt on my kart before I change gears. Other then changing tires does anybody have any advice?
 
I suppose it will be good for seat time but your sprint kart will not be competitive. I'd start with an inch stagger and moving the seat as far left as you can.
