If you are competitive and are looking to enjoy a competitive go cart experience, don't go to Octane.
I would say that I'm a go cart enthusiast. I enjoy the racing part of go carting. So, I am a bit competitive and like to try to turn fast laps. With that said, my opinion of Octane is that the carts are very sensitive to driver weight. This makes all the difference in these carts. I weigh 220 pounds. I was driving what I considered to be a good attempt at fast laps. Compared to a 120 pound woman, she could out corner and out accelerate me no matter how well I drove or no matter how poorly she drove. It was frustrating to me.
If you don't care about the competitive side of go carts, the place is great. The people were friendly, and it was very clean. I prefer K1 Speed. I have never had any issue with those carts from a competitive standpoint.
