Ladder Bar question

Been monitoring this out of curiosity. Built some drag cars or parts of them, but never tuned one.

It's a very good idea with any race car to have a log book. At the vintage road racing shop that I worked at we used one of the "5 topic" spiral-bound binders. One topic was dedicated to notes from days at the track (suspension settings, engine tune, etc., etc., etc.). Another was concepts or forward thinking and such. Another was for sketches of what we were about to make or do with/for the car. Can't recall how, but we managed to use every topic and wish for more dividers. We used spiral bound specifically so that pages could not be removed and lost. We considered the binder to be an integral part of the car. The only place that it did not go with the car was out on the track. It lived in the car the rest of the time and went with it when sold.
