Your alignment specs look good, but you need to realize that the negative camber will normally wear the inside more.

There are only two sensible solutions given your informantion:

1. Set the alignment with less negative camber.

or

2. Dammit, corner faster!! That will even up the wear with those negative camber settings!!

Keep the toe within the normal specs. Trying to compensate outside of that range will only wear the tires faster.
