Guessing I need an alignment...?

According to everything I have read when autocrossing or other hard cornering you do need to up the tire pressure somewhat. How much seems to be less clear. According to my wheel guy extra pressure also helps to minimumize wheel damage when we hit the inevitable potholes, etc. As the economy worsens and governments cut back on road maintenance we are getting more road hazards out there. Since I do most of my driving on curvy mountain roads I add about 4 psi to the recommended pressure on both boxsters and my C4 and have found better response and more even tire wear with less wheel damage. Just my experience. Try a few things and do what works for you.
