yeah swingouts are allowed. I thought I remember John saying something though about possibly not even needing those side bars. I can't remember and I think I deleted the PM's. Deng it.
EDIT:
found the PM. He said with a 10pt cage, you only need a drivers side bar. So you could leave the passenger side without a bar, and only have a bar on the drivers side, but have that bar completely removable (via pins like a swingout), and leave that bar out all the time and only put it in on track day. That'd probably be your least intrusive option.
So something like this, but that cross beam that goes across the driver side door could be completely removeable, and the cross bar on the passenger side door simply wouldn't exist.
