N00bie question re: negative camber

[red_wagen]

Hi, this will be a series of threads/questions by me which hopefully culminates in my getting my own Boxster. Anywhoo regarding the negative camber on the car, I understand leads to premature tire wear. Is there a way to adjust the camber so tire life may be extended a bit? I understand, correct me if I'm wrong, that the negative camber is there to aid in high speed driving. But if I drive smart and keep my speed under the century mark is it possible to adjust the camber? Bear with me and my n00bie questions as I know close to nothing about these cars and I want to research as carefully and as much as I can. TIA.
