I have actually seen this happen twice.
Once was years ago... it was a formula SAE car that used to run with our local SCCA region. It was not a lug nut failure, it was an engineering failure. the axle broke at speed and the wheel took off across the course. I chased it down and kicked it to slow it down and change it's trajectory so it wouldn't hit a kid in a stroller. At the last AX of the season here, we had an MR2 Spyder lose the right rear wheel. The owner added wheel spacers and race tires AFTER tech, and he was using the stock aluminum lug nuts. They did not have enough thread engagement with the spacers. The amount of G forces he was pulling was too much for the "two turns of threads" he said he had. Turns out that it was, in reality, two 1/4 turns of threads. Ruined the fender, the taillights, the rear bumper cover and a bunch of expensive body parts. It can happen, especially if you are stupid.... |
