Tire temp across the rear tire should be used to set PSI. Even temps “generally” mean correct PSI. Changing track width could require different PSI.
As Mr Lawson said, using temps to set front camber is a good strategy. The front end geometry will affect the handling and best handling may end up with uneven tire temps and quickly worn tires. I always try to get the front geometry correct first by looking at the handling. It takes more time and experience as someone said above, Karting requires different chassis tuning to be fast. It is even different from Sprints to Enduros.
JT, a new model coming?? I need to get some training to expand my basic understanding of sorting through the data. I will look on line.
