Stop in for a cup of coffee

So will SCCA for most, maybe now all, W2W racing.
What will matter is what the inspectors see on the car. SCCA itself does not certify or approve equipment. They will check what is on it, including your personal safety gear before you race. Some regions set up pre-event checks. Probably should go to one and observe.
Yeah I went back in November and watched and asked questions. Plan to do so again next month
