Camber adjustment info from Lexus rep.
I just got back from the Lexus dealership. While there I asked how they can lower on F-sport springs and keep the alignment so as not to wear the inner tire. He knowledgeably explained (and showed on an exploded view of the suspension) that there are replacement camber bushings for the front that are available in + or - to counter the lack of direct adjustment. They run $180 for the set. As for the rear, he showed the part labelled "cam adjust", so the bushings are not needed. Was he full of @#$& or is this true about the bushings?

I went back and talked with a different guy who said the same thing. The part numbers are 48075-30040 (+20 degree offset) and 48075-30050 (-20 degree offset). It is shown in orange in the pic below of the front suspension. I don't know how it would work, but that is what they said. For the rear, the orange rod is for some cam adjustment. Apparently it has an oval slot that can be slid in/out and the bolt then tightened for minor adjustment. He didn't know how much lowering it could actually help correct though. Hopefully this helps.

I know that for the LS430s you can replace the bushing for the front lower control arm to adjust camber/caster, if you think about it, the position of where the lower control arm will affect where the knuckle will sit thus changes camber/caster.
As far as the rear, if you notice that arm, it goes to the side of the knuckle, only able to adjust toe. to correct camber, you're gonna have to either adjust the top or bottom of the knuckle. on LS430s, to adjust rear camber, a replacement arm is available in different lengths to adjust camber, either (+).75 degrees or (-).75 degrees.

I can perhaps see that the front's could be adjustable with a bushing but for the rear, that's STRICTLY a toe adjustment netting ZERO effect on the camber. It's obvious where the arm attaches to the hub assembly. Plus, looking at the rear suspension on my GS in person, there's on way.
