No, lower pressure at the rear means less tendency to slide in the rear, so you get understeer. I'd say start with 36-40psi all around, go out for a few laps to familiarise and then do 2 hot laps. Then come back in, measure all 4 corners again. It should something ridiculous like 50psi because of the heat. Then adjust up or down to suit.
