street tires at the track - any tips?

Thank you guys for all your advice, i appreciate it...:newb:

I have 4 days left to check everything, so there´s time to find the "biggest footprint" pressure. At the track i´ll make a run with and one with out burnout - will make a "logbook" to write down the changes and then i can see what happens to the ET / 60 ft. times. The front tires are already at 40 psi.

Thanks again!
