I'm not quite sure I get the value of the continued discussion. Even if you continue to use 12mm studs, for whatever reason, I consider the studs on your car now compromised. What CAUSED the bending can be argued, but for the application, don't keep using damaged parts.
I do wonder about the wheel aftermarket, which seems, nearly always, to quote lower torque values for (their) wheels than what OE specs are. Whether that is a lowest common denominator situation, with wheels that fit a multitude of applications with studs as small as 7/16", which DO specify a lower torque value than 12mm, or whether it's concern about the quality of their wheels when torqued beyond a certain value, and 100 lb/ft was not considered "safe" for their wheels. Could be mere supposition on my part.....
I do think Michael's comments are spot-on, and do a good job of taking what I'm thinking and TRYING to say and putting it through the engineer's mind and making the language match the reality of what is going on.
Regarding lube or no lube, my only concern is the need to have the studs properly tensioned to clamp everything as designed, which would preclude the possibility of the studs bending....personally, if a lube WAS to be used, I would go with a spray moly-lube "one time" and leave it at that....that is to say, continual re-application of lube would be excessive in "my world".
