Oak hill is a Kart track. Your gearing should be fine for that track..
The gearing I ran yesterday was 15/42. I will put on a 45 for next week at Oak hill..
Go to CMRA and you can find all the track days, Ridesmart..Lonestar track days.
Eagles canyon is having a day in july. That's up in denton. You will need tall gearing for that. I will run 15/40 for that track..
They cost about $100 for a track day.
You can ride racer group with me and we can spank on the 600's..
