It depends on the track and how fast you go. My local tracks will allow you to run with no equipment at all with my car and even ones running 9s. I ran at a couple of events in Bowling Green that didn't require me to use anything but a helmet that they didn't check, then went to LS Fest there, and was told if I ran faster than 11.5 in the quarter, that I needed a 2010 up approved helmet and a fire jacket. My helmet was too old and I didn't have a jacket, so I found a couple nice guys that let me borrow their helmet and jacket to get through tech, then only wore my helmet during my runs, and no one said anything. So the event organizers may also have different rules from what the track will normally allow.

I would say at least get a helmet. I think you can run open or closed face, but I'd recommend a closed face. You can leave your visor up for air. A fire jacket would be the next item to get in case you need it. The best thing to do would be check with guys that run at your track with a similar car.
