These are the same tire temperature data sheets that Kenny uses for testing and race weekends. Each datasheet, which is designed to be stored in your logbook, is a critical form used to record the basic information about the car's setup before you go on track.
When you get off track this form is also used to record data for tire temperatures and pressures, along with other information such as lap times or performance-related information from the session. This is a fundamental resource that you will also use and refer back to during your next trip to that track, or in the same type of conditions.
Sheets are 8.5 x 11 inches and have an adequate margin for a common three-hole punch making them easy to store in your binder or notebook. You know, the notebook you should always have with you for every track event where you record important data to make your car better.
