Kenny's Notebook Rule - Always Keep Good Notes
Kenny always preaches how important data is, and how important keeping good notes are. When you are at the track, you're recording tire, shock, alignment, and a host of other data.
Having a good notebook will help with the future car set up when you go back to the same track. You can establish good starting points from previous data and get up to speed much quicker.
