Finding your class can definitely be a confusing task. There are so many available and custom modifications out there that it can become a bit convoluted.
I recommend using one of these cheat sheets to get a general idea of which class you fit into. Then go into the actual SCCA rulebook and confirm it.
First – Cheat Sheet – Note that this is an older document, and some things may have changed. This is intended to be used as initial reference and guide to finding your class.
This guide I find very useful to getting a general idea of classing:

Second – Confirm your Class – This is the official SCCA Classing Guide. Click the link below, and scroll down, then click on the class you believe you are in. Read the section and determine if you fit. Sometimes it refers to previous sections and other classes rules that you will have to go back and review.
