36/40 wether fully loaded or not, only time I do different is trackdays!

What pressure would you use on a track?

First session I went with a recommended 30/30 cold which sucked balls, 2nd session and all sessions after were 32/34!

I s'pose heat, expansion and a nice even flat service majorly changes things.
30/30 must've felt like a golf cart!
