It looks like I may have to visit my wife's family in NC in April and a race at VIR might make the trip livable for me.

What do I have to do to my ITC Civic to allow it to run in HP? I don't want to show up at a national event and not be allowed to run.

The three things I can think of are:

Fire system: my handheld is no good in prod?
Fuel cell: my rotary moulded cell in a metal can is no good in prod?
Window straps: for some reason I thought they were required in prod?

Honestly it seems a little silly that my ITC car is legal to run in a group as an ITC car but if I switched to HP and ran in the same group it is not technically legal. I don't suppose there is an official ruling that says that if I run my car in legal ITC trim it can run as an HP car?

I guess my other option is STU, I'm legal there all the way, right? Makes no sense since I'd be running against bigger, faster cars, but...
