for me, i will stick with the psi listed for the car. i see no need for a street driven Z to have more or less in it at all. put too much in you can damage the tires and the suspesion, too less and you can damage the wheel along with really bad. now + or minus 1-3 psi is not a big deal but 5+ either way is not very good. but then again, it's your tires/car do what you want with it. you like replacing parts/tires then go ahead
