As the photos show the front attachment nut plate has fatigued and fractured. It looks like it has been that way for some time based on the corrosion along the fracture line. The design looks a bit frail for me but it seems to have worked on many race cars.
My question is what have people done to improve the design of the part? Have many of you found the same problem? It isn't as simple as welding on a thicker plate because the control arm would toe out. I thought about welding on some small gussets but there isn't much length to weld along. I would appreciate your help.
