Hopefully I can get some help for my concern...

Here's the situation: I've never raced much before, and never at the track. Tomorrow night they are having open racing at the local track (only 1/8 mile). There are always quite a few imports out there and I'd like to join some of my friends racing. But, this is my only and daily driver, and I don't really want to have it down for too long fixing broken stuff. I can if I need to, but, you get the point. So, my question is should I be worrying much about breaking anything? Or should I just stop being a wuss and go out there. Any help or comments appreciated. Btw, I have a 94 Civic EX manual with bolt ons and lowered. Thanks
