In my experience running a street/track combo BSX Boxster (225F/255R tire widths) that I drove to work everyday and did over 30 track days with, I found that -2.75F/-2.0R camber still isn't nearly enough.

Sure, its better than -1.5 but ultimately the outside portion of the tire is still what wears out first. Ultimately, you need more than -3 to fully compensate for the camber curve of the Boxster strut suspension.

Other make/models will, of course, cause this to vary as will tire selection, driver skill/technique, etc, etc...
