Interesting that you went lower in the back - I was just the opposite, as the lower pressure in the front helped them grab better. I started the day at 34 PSI COLD. Tires were all up to 42 after the first session, then I went down to 38 in the front. Made a BIG difference and the car did not push nearly as much. Figure COLD pressures would be 30 front and 34 rear.
