Check the rules for that specific class. Because that’s not true for a lot of the classes out there, and the rules are totally different depending on the class. For CAM-T you can do darn near anything.
Also, it depends on what your goal is. If you just want to have fun, it doesn’t matter what class you’re in. You won’t win any trophies if you end up in a really competitive class, but if that’s not the goal it doesn’t matter. If the goal is to win in a specific SCCA class, it doesn’t matter what works best, you have to follow the rules and they don’t always make for the best upgrades or car. Just a level playing field.
