At VIR, you will need long sleeves, pants, closed toe shoe and a helmet. I was at VIR this past weekend as the guest of a VIR club member...attached is there tech inspection form and the requirements...which are pretty much the same as I have seen at other club events there (e.g. Ferrari, Audi, Car Guys, etc.). I have not heard whether we will have our own form or not...but this should serve as a starting point. By the way, our 5-point harness is fine. Some car clubs have their own rules, which may be stricter than VIR, but not "looser" than those requirements. For example, the local Porsche club will not let me use our harness because the submarine belt does not pass through the seat...so I don't go to their events.
