Another ADV.1 Quality Control Failure

Reason being is that the thin metal is only about 25-30% of the round hole, which means it is impossible for the bolt to "pop out" of that hole, and when you have forces distributed to so many holes, chanses of that failing are extremely minimal. I am an engineer and machine all types of products for a living.

Now, do I agree with them? No. For me the safety and vibration issues are due to the multi-piece wheels themselves (because of the possibility of human error when assembling, like overtightening/leaving the bolts too loose), and no matter what, this is a brand new production wheel, not a prototype...It should have no mistakes, should of been scrapped just because it is not to plan, regardless if it will do the job or not. This is a careless error and these are not cheap wheels where something like this would be "understandable". $8000 to me is a ridiculous price...these wheels should be beyond perfect.

As an engineer, I would actually think if the rationale showed it's still good for use-as-is, the initial cost of material may be prohibitive, and they can provide the rationale and move on. I still don't agree, given the price I can't figure out how they couldn't just buy more metal and redo it, but just saying.
