I found these on MCM:

For best tire wear, here is what I use on all MM alignments:
Camber: -.3 to -.5 degrees.
Toe: Zero degrees.
Caster: 5-6.5 degrees positive with .3 degree lead on the right side.

These are the ones posted on MM.net:

For best tire wear, here is what I use on all MM alignments:
Camber: 0 to -.3 degrees.*
Toe: Zero degrees.
Caster: 5-6.5 degrees positive with .3 degree lead on the right side.

Which one is correct?

I have only ever seen the Camber spec at 0 to - 0.3 degrees. That's the one that I have written down on a 3" x 5" card and put in my owner's manual.

Here is the NOTE for the asterisk in "carfixer's alignment" ....

Camber: 0 to -.3 degrees.*
Toe: Zero degrees.

*Camber can affect cornering feel. The more negative camber you have, the better it will handle corners. Most drivers will never feel the difference, especially on the street.

Maybe MCM went more aggressive on the cornering. :dunno: Probably helps in avoiding those Detroit potholes. ;)

This is the reply by PM that I received from carfixer. I hope he doesn't mind me posting it.

"George,
For the past couple of years, I have been setting most to -.3. The biggest cause for tire wear in the factory alignment has been the toe out. It gets compounded with the negative camber. By taking the toe out away and setting the camber to -.3 to -.5, you eliminate the tire wear issue and retain the handling. I hadn't been too active on this site for some time and didn't update it. I will have the mods update the document.
