Tire pressure for Michelin Cup Sports?
Getting ready for my first HPDE with cup sports. The manufacturer's guidlines say Front: 25 cold, 32 hot, Rear: 28 cold, 36 hot. Can anyone with experience with these tires give me a better idea for good pressures on a C6 Z06? Thanks!

thats about right for a normal 70 degree day 
i am in phoenix and i run 26 front and 29 rear up to 80 degrees then i lower it a pound over 85 and 2 pounds over 90, after that who knows!
in the cold mornings under 50 i run 29 on all four corners and drive slower
watch your wear patern on your side walls. if it wears to low add air and vica versa

If they are new tires they'll take a few sessions to get broken in and wont get up to temp easily at all.
And yes, very slick when cold, so take it easy for at least a lap or two in the early sessions.
