Starting pressure for first session at the track is 34 front, 32 rear. Hot pressures coming off the track are 38-40 front and 36-38 rear.

That is strange you are getting that wear on the inside like that. What is your front camber?
On 245/40/17 I was usually running around 35psi hot with that tire though your different specs may change things a bit. I’d say temp probe them next time and see if you are getting abnormally hot in those area’s. I just don’t know what’s causing it and their explication doesn’t match what I see. To me, your pressures seem too high and usually unless you are running well over -3 degrees of front camber these cars tend to tear up the outsides off the fronts.
Here’s a pic of my RT’s after 4 track days. Wear is on outside edge even with -3.5 front camber.
