Since you seem to be open to varying opinions:



1. So whatever forces the balljoint inputs upward, they are resisted first by the flat section surrounding the balljoint, which will flex, to what degree I don't know, and the bending forces will be also resisted by the two 5/8"? attaching bolts in single shear that mount to the spindle, correct? Seems Like thickening/adding a web/etc around the balljoint would stiffen this area, reducing the bending load.
2. Is this billet or welded?
3. The steering arm web is IMO way over kill, the way I see it the arm mainly needs to transfer steering inputs, which I also think most grossly over estimate, and resist the twisting induced by the bump steer standoff correction. Your large/long web is not the ideal solution for those two scenarios.
4. It looks nice.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
