Went into a corner hard braked in a straight line down shifted to 2nd turned in back to throttle Understeer curb on outside slight lift car neutral then small oversteer with the aid of PSM. PSM off could have been a different story.

Should I have increased throttle to i decrease Understeer? ie: more weight to front tires?

 

One of the greatest things in a Porsche is it's ability to trail brake. Cars with proper alignment and properly driven won't understeer.

 

Ditto. What are your alignment specs?

 

Completely stock 09 C2 with 19" OZ wheels. Enlighten me with the proper setup that is still a daily driver setup without destroying the tires.

 

Sounds like a driving issue. Probably release brakes too quickly (and then power) resulting in understeer. 911s oversteer with throttle lift when loaded.

I would be somewhat surprised if it was an aligent issue. You probably aren't going fast enough on the street to notice alignment while driving, although overall tire wear might give something away.
