Ball Joint extra camber eccentrics

[GS guy]

I was able to get somewhere just shy of -2 degrees on my mocked up BJ front end. A lot is dependant on how well centered the beam adjuster is. There's enough slop in the (avis) adjuster grub screw fit that it's easy to bias a degree or so towards one side or the other.
Rather than bend the arms, you can flip the upper torsion bars over and re-drill the outer grub screw locations a little further inboard. You're only talking about a degree or two, which means careful measuring before drilling. I think if you need more than that you may need to do more to limit body roll.

Thanks for the info Jeff.

I did some measurements last night. It appears that the BJ is offset by 3.5mm more when using the extra camber eccentrics. Given that the distance from center to center of the 2 BJs is about 170mm, that should give about 1.2º more negative camber.
The car I am working on has zero camber right now. I don't know if the alignment guy set the stock eccentric to max neg camber.

I know a guy who built some UK aircooled cup cars - on all of those he bent the top arm in a press to give 2-3 degrees neg camber (can't remember the exact value)
