If you have multiple people with your car in tech you will be subject to being disqualified from that event and scored in last place. We do not need people running and telling us what to check, and causing issues in the tech area. If your with another car and come telling us what to check on someone else’s car that driver is subject to being disqualified, basically mind your own business.
