Track tire pressure - at start and finish of session

[Sboxin]

I agree with 944boy -- except front =33 and rear =35 cold temps.
The 2 pounds difference between Fr and RR helps with the Boxster balance.
And, try to keep that log of temps and pressures so you can set the pressures at off track hot temps.
The R888's take a couple of laps to heat up, but after that they do stick very well!!!
Keep an eye on your power steering; this can fail and blow PS fluid all over the engine and exhaust if the fluid temps get too high from the R888 tires (look at my previous posts from 2007).

Enjoy!
