As a consulting engineer occasionally asked to assess the liability of major retailers selling and installing tires or performing brake maintenance, after which a wheel comes off the hub, I once ran the following test:
My old Silverado with aluminum wheels with 5 lugs had a 100 lb-ft torque spec. I torqued two of the non-adjacent lug nuts to 100 lb-ft, and the other three to 40 lb-ft, and marked all of the nuts to determine if any would move. I drove for 4,000 miles with this configuration, and none of the nuts moved from their original positions.
Thank you Chevy engineers for the robust factor of safety against less-than-perfect maintenance practices.

As the owner of a 2015 center-lock 911 GTS, I concur with all that has been written above. A total PITA for no benefit, other than a racey-looking appearance. Love the car (as I do my C7 Z06 and upcoming C8), but regret being lured by the center-locks.
