Just wrung what you brung and don't sweat the details at first. For your first several races you will be put into the amateur class to start out with. If you know how to throw a car around and yours is well sorted out you might even be able to win your noob category.

Way back when I started you either had to run about seven races to move up to your class, or just win the noob class a couple times. For that reason I got to run the novice class only a couple times, lol.

Having raced a modified porsche for years I'll admit it wasn't easy. in the ASP class I had to run my old school turbo that didn't even have ABS or traction control up against new modified supercars. I sometimes got my ass whooped and had fun anyways, but it was also extra satisfying going home with a first or second place trophy after running up against some of the best of the best.
