Fabricated A-Body spindle ideas and discussion

With a hub assy made for a spindle as part of the knuckle, the hub is rotating with the outer race. A driven axle has the hub rotating with the inner race along with the cv stub or bolt and machined washers you were describing earlier. Not a huge difference in weight but notable.

The GT350 uca pivot is lowered to increase the camber gain. The arm has to be shimmed outboard to keep the same camber setting, but it pulls the ubj inboard more in bump, less in droop due to a falling ratio. A generally good angle for ucas is around 7 degrees from level for a virtual swing arm pivot just outboard of the opposite side tire.
