| Excessive torque on the 5-bolt wheels will warp them and the drum permanently. |

Similar for most wheels, drums, and rotors, on all vehicles. Know the torque values, and pay attention to them.

Yes, but I've found the wide 5 design particularly susceptible. That may be one reason VW went to 4-lug with a beefier center. |

If you're ever using any of the new wide 5 drums DO NOT go over 75ft/lbs they will strip.
It doesn't matter if they are cheap Brazillion or "OE GERMAN" the cast iron used is shit. I have 3 sets of rear drums from all different suppliers and qualities. They all have Wurth-serts in them to repair stripped threads.

If you have new aftermarket aluminum rims re-check the torque every 50 miles or so for the first few hundred miles as they tend to come loose until they are worked in.

Is the damage done simply by the over-torquing, or does it occur once you start driving around on the over-torqued lug nuts? |

Warping happens if/when the bolts are not torqued in the proper sequence. This can be made even worse by over-tightening, or not applying the same torque to each bolt.
I usually snug all the bolts up with a ratchet, then torque each one to spec. Start at one bolt, do the one opposite next, then continue like that with all five.

The reason I ask is the company I hired to put new tires on in order to have it shipped cross-country to me, I believe, substantially over-torqued them.
It was put on a trailer, shipped, and was never driven with the wheels in that state. I assume I'm in the clear regarding damage? |

My theory is that the wide pattern was viewed as a way save metal. In the late '30's era of drum brakes why do the stamped steel wheels need to go almost back to the hub? In that era Ford, and others, tried the wide 5 pattern. Most (except VW) went back to a smaller pattern within a few years. Torquing the bolts so close to the drum face seems to make them uniquely likely to warp. More so when the stock style steel wheels with "ears" bumping out to each attachment point are replaced with something more rigid.
The old street rod use of Ford wide-5 drums was a big part of the reason I went with stock and widened stock steel wheels on my Mini-T buggy. It's both traditional for buggies and a nod to its street rod styling.
