Regarding Doctor Gollums personal preference about the front wheels camber, for my experience there can be added little more negative camber to front without having uneven tyre wear. In my daily drive I´ve got 1´56 and in my V6 even 2, only problem that the car is too willing to turn in

A little example about the V6 from the last summer:

Those aren't my settings, but those that Tony created for the Omega at WIM, And yes, I used them on all my Omegas.
That your car is too willing to turn in tells you that the geometry is wrong. Set up right, the Omega is beautifully balanced. And perhaps more importantly, stable.
Making the car more understeery doesn´t make it particulary more stable
When your front wheels lose their connection to tarmac/road, you´re lose the incoming feedback as well.
With the fine tuned settings, I never found the Omega to be either understeery or oversteery. Just neutral and balanced, with just enough toe to counter the natural dead spot in the steering box
Making it turn in more easily makes it harder to remove steering lock. That said almost all my driving is on paved roads and not snow or gravel, so perhaps your geometry works better for that.
