Last weekend started at about 24 psi at Cota and it got to about 33 at end of 20 min session. I found that around 29-30 hot (based on in car tpms) is the sweet spot for me! After that it tends to get greasy and lap times suffer as a result.

Hmmmm, I've been running about 33-34 hot....I'm going to try 30-32 this weekend.

Would like to know how that worked Martin!
Was at SOW and ran 32/33 F/R tires felt great but pushed
later in the session.

Interesting...what tire sizes are you running? I have 265/35/19s and 285/35/19s which helps with the push considering I have the BBI higher wing uprights.

245/40/19 285/35/19 ( not enough neg for 265's )
