when looking for hot tire pressure. what are you looking for as a good reading. lets say i started with a 32 cold front and 30 cold rear. i know it is different tires work under different temps.

generally you want to see a ride of 5-7psi cold to hot. If you use warmers for the specified time, you should see a 4psi gain and then off the track and additional 2psi gain. That requires your in lap to check pressure is fast as is your hot pit speed (following track speed limits of course!).

I really appreciate this approach. I've learned more watching your videos than all of the suspension books I've read put together. Thanks!

That says a lot so thank you for taking the time to reply. If you don't mind sharing the video's we can certainly help a lot of our community this way. I'm looking to make about 80 more videos before the end of the season, posting every week. Cheers!

Very nice. T-Hill is an amazing track. Been on it since '98 when it was 1.9 mile course. Great vid and commentary

I just bought the S20R tires for my trackday this Saturday. What tire pressure are you running here?
