Only the best for my baby. OEM Stuttgart-made N1 spec air for my tires!

Full load at autobahn speeds....

 

Last year the chief instructor for the Metro NY PCA Region gave me a hint as to where to set the "cold" tire pressures before the first run of the day at Watkins Glen. Each wheel was slightly different, somewhere between 32 and 35, if I recall correctly. He said that all four tires would be at 39 psi when hot after the run. Then I could add/subtract 1 or 2 psi for each according to how their "stick" felt. He was correct; all four were at 39. Unfortunately, I kept making adjustments as the ambient temp gradually went up, thinking I was getting into the "zone." I should have paid less attention to tire pressure and a bit more to the driver, as usual.
