Levels will vary on tire compound, size, what you're running on, how hard you run it...etc
If you're really pushing it, a good indication is the tire arrow:
Those are my RS3s after my first auto-x. The arrow indicates where the roll-over mark should be. All tires will roll over the sidewall, adjusting pressures to make sure they don't roll over too much/little is key.
I dropped 1 PSI in the rears and now I'm golden. I run 35 hot rear, 39 hot front on my RS3s for autocrossing.
