I am putting two new rear tires on my 2003 S after the current set expired from excessive wear on the inside of each tire. I expect this is caused by excessive camber but I don't actually know. I have heard that Porsches often have this excessive wear pattern because of the design of the suspension.

Is this a fact and should I expect this kind of poor wear in the future? Or is my car so much out of alignment that this is the problem? If it is a design issue can you set the alignment .5 to 1 setting over the factory recommend setting in order to solve the problem?

I think the tires were relatively new as they were on the car when I bought it and were the second set. The car only had 21,900 miles at that time. I've only put 4,500 miles on it and they are pretty shot.

Any advice is welcome. I am having the work done Wednesday, 8/04.
