I welded to cheapest hub at the closest place I could find. Think it was some shitty 4 stud 4" pcd cast iron thing from supercrap.
I cut all the stuff off and preheated it, and cranked the welder right up.
Chinese bearings died way before the welds looked like failing.
You could look for a cast steel hub.

Cut if all off and the car improved significantly.
