I would get you a used open car trailer, and find a car you like, whatever that is and start bracket racing, as you go add to the car or truck and go faster and faster as you go, I wish I would of spent some time bracket racing in sportsman et, that looks like a fun class, and then move up to pro or super pro as you get used to your ride.
I myself started out in the mid 15's and now have gone mid 10's and getting there as been quite fun, I value my first 12 second slip as much as I do my 10 second slip
most of all get a car or truck or whatever you want that you enjoy, something you want and get out there and have fun, you dont have to go 9 seconds to be cool or have fun, its all fun as long as you are racing
