Would camber help in the rear? I remember Rusty Wallace of NASCAR got caught using some sort of trickery to camber the passenger side wheel on the rear. I never saw how but my thoughts were full float rear and a CV inside. Certainly this could help a solid rear perform better to a small degree.

Oh I am excited to see the return of the Flying Green Brick. One of my favorite cars and stories.

So something like this could add some toe in also.
