I am not familiar with your track, but I would start with 15-18 driver. That will get you in the ballpark. I did use a 19 a couple of times last year, but those were special cases and you could get away with an 18 and a smaller rear gear if you had to. On the rear, I would say 60-65 will get you started and slowly spread out from there. Look for gears in buyouts and at swap meets. You can find them super cheap.
