Getting a logbook for your race car
First of all, find which sanctioning body you plan on competing with and read their rulebook carefully. Once you have decided which sanctioning body you want to go with, contact their chief scrutineer who will put you in touch with your local scrutineer. The local scrutineer will usually ask you for pictures of your build to make sure the main components are in place. When you are ready for the logbook to be issued, you'll have to get your car inspected by the scrutineer who will check the cage tubing, footings, welds, gussets and anchoring points for the seats and belts. If everything checks out, you will get a fresh logbook for your car.
The service is typically free but if you have the scrutineer come to you, you'll usually have to pay for the travel and time.
