SCCA?

Does an F3 car fit in any SCCA class?

FS.

There are many "F3" variations. I believe most can be made to fit within the FA regulations as well.

You will have to go through the homologation process and they may or may not want the roll bar changed. When I bought mine I was considering a dual FS/FA homologation but have done nothing about it.

I am curious about this as well- anyone have more details?

Thanks-

Read the FA rules section of the GCR. They can fit into FA, but you will need to work with the club.
