This beefed up version of the front bearing hubs preserves the original wheel bearing fitment diameters but beefs up the screw locations.  It uses M4's for each location.

 

The other beefed up version used a M3 at the steering link which I found added slop to the joint unless you change the steering link hole to an M3.  That version also increased the diameter of the bearing seats which also increased slop.

This version reduces total wheel wobble from the other beefed up version while also increasing strength.

The other beefed up version removed the chamfers on the sides of the suspension mount which decreased the load carrying section and increased the stress concentration which lead to some failures for me.

The attached picture shows my version on the left with the other beefed up version on the right.
