Otoh, reading all that might make one wonder how older cars, with less careful techniques, ever rolled down the freakin road, lol!
There are even TSBs from other car manufacturers talking about braking shudder, etc., from improper torque.
My orig comment to the OP was simply to remind him that a good wheel joint can change tires w/out putting any marks on rims, and that proper wheel lug torque is important. I was not trying to crank his, or any one's paranoia. But, the guy cranking on the wheel lug bolts/nuts with his impact wrench may be the same guy gouging the crap out of one's wheels when changing tires...a good Joint is worth the hunt, imo.

Torque wrenches have been around a long time (circa 1918) so there has been no technological barrier to the use of them in the last hundred years or so.
Newer cars have made advancements in NVH which may make other things more noticeable. Also, the use of front disc brakes have not been prevalent until the last 25 years or so. This allows lug torque to affect braking performance to a higher degree than drum brakes.
As far as wheel lug torque is concerned, ideally they should all be to spec, but I think being consistent is more important than the actual number (within reason of course).
