Under-inflating my Cup2's dramatically helps lap times in my GT3. Start pressure 25 front and 24 rear come in and bleed down after a few laps to maintain high 20's. Also on my 991 Turbo S low 20's in the rear gets the car to hook up on launch control 0-60mph in low 2's every time. At the manufacturer setting the tires spin wildly. So yeah, lower pressure = larger contact patch = better performance.
