Seeking advice on how to extract broken lug bolts

That's saying a mouth full right there.

I guarantee most lug studs have been over torqued in their life and I bet 50% of all A body 7/16 lug studs are currently over torqued.

Almost every bolt on today cars has a torque spec. Some even have a "one time" use, as in head bolts and lug nuts. I just did a spindle change on a VW and all the attaching bolts have a torque spec.
