The toe setting is very critical. I think that the BFG tires may be a little more sensitive as well.
It may help to reduce the negative camber. Doing so may hurt your handling when cornering, but I don't think it would be significant. You can adjust the camber by installing adjusters like BAT sells. The front struts must be removed to install them. I have not done this yet, but I intend to do so when it is time to replace the front struts. I would like to see the front camber at about -.5 to -.25 instead of the -.8 and -1.1 that you now have. BAT is not the only source. I found them locally for about $45.00 each.
In the mean time, check the alignment frequently and keep the toe near 0.
