I agree with JBo,
I had a wheel nut come off an AC MK IV on the way back to the hotel at a SAAC convention.....................after having put over 100 miles on the car at the Pocono track! I saw a glimmering flash fly off the right front and into a newly mown hayfield! Three hours of searching located only grasshoppers and cow flops!
I got the car stopped before the wheel had walked off the hub.......bigtime scary!
Hell, safety wire the nuts BOTH ways and then you will never be wrong!
