What are recommended tire pressures for stock (non R) tires on the MS3 for autocrossing?

I would guess in the neighborhood of 46-48 for the front and 40 in the rear, am I close?

A good place to start. Put some shoe polish or chalk along the sidewall and tread to make sure the tires are not rolling over. Make 2 PSI changes until you are happy.

BTW, use a gauge that reads up to 80 PSI as gauges are the most accurate in the middle of their range.
