As a teenager I used to give my RP beans, regularly lifting a rear wheel on a switchback corner on my way home each day. I managed to find a set of studs not dished at the back or stretched to Whitworth but was still nervous so fitted 3 extra. Skills and tools then limited and did not get sufficiently accurate for cone seatings so settled for flat.
As with other cars with 3/8 studs have to stand guard over tyre changers and “mechanics” accustomed to the astonishing torques of moderns.
A common cause of failed studs is wheels which work loose on thick paint or dirt, causing fatigue failure of the stud, as in this case. Or seated on the brake drum screws.
It is so common to see studs dished that sort of expect at least one of to fail that way, but not so in this case.
Incredibly the rear guard, so often bent one way ot the other on RPs, escaped damage.
Also surprised the car did not lean more obviously. Does not seem to tilt at the initial lurch.
