There is a range of recommended settings for camber, castor, toe, etc. You can dial those in at the limits of the setting for best results for autocross type handling without effecting the highway use.That is how I have my 928 set up, at the best handling settings within the factory limits.

And I understand what you are talking about. Even at the stock settings my Boxster was so twitchy at high speeds It was not what I considered safely driveable above 120mph..It was happiest at about 90.
