on the street , day to day driving Im running close to 35 cold I believe thats whats recommended by Nissan...
drag strip anything from 20 - 25 in the rears , fronts I leave alone..
never been autoX yet..
At the track I normally start off around 31psi cold, and by the end of the session, I'm usually over 40. I then bleed out some air and keep it around 34psi for the beginning of the next session.
