By popular request, the race is going to have zero damage multiplier and invulnerability available. If you want to use invulnerability, press F6. If you don't, your car can still be damaged -- even with the damage multiplier at zero.
If you're having problems with Teamspeak, leave it off entirely. It is preferred so you can hear what is going on and keeps me from having to do one more thing while running video, act as spotter, and the event, but if it is causing a disco and/or interference leave it off and watch for text messages.
