Auto-x Tires pressure?
First event 996TT. thought I would start with 40-42 reat 36-38 front. Dunlop Super Sports came with the car 235/18 285/18. I have a pyrometer
Any other suggestions?
Thanks Steve

You're going to understeer. Try 40 front, 39 rear. Get someone to take temps
immediately as you exit the course. They call them out, you write them down.
You may find the tires get sticky then get loose if they're too hot. Bleed aire
to keep the same pressure at the start of each run.
It sounds like you have no time for serious fiddling, but if you want to stick,
you need about 2-2.5 deg negative camber in front and a half degree less
in back.
*TURN OFF PSM*. For autocross it will intterupt unnecessarily. The car
will feel *much* more intuitive with it off. Use your AWD. Get on the power
coming out of corners.
Have fun.
