Help Me Fix Alignment Please

You tried the plastic shim and it failed I'm not understanding that? The shim didn't fail I guess it's do far out . ? So then bending it back is it .,? The manual say no adjustment . So maybe the manual was written before they made shims I'd be interested to know which way bad,? You had too much neg camber do it got towards 3 degrees would be worse if it went towards below the 2 degrees it would be getting better . So the shim at max isn't enough to bring it to spec it seems . I would love to see the scan of your alignment of getting worse .

 

Seems to me you be trying to pull down on the beam . Which you might do with long iron bar in the bearing hole . Or plate attached to lugs .
