Ford J car

[6R07mi]

It is my understanding that experimental chassis 'glue' broke free (due to vibration) causing the Miles car to break apart. 
Heard this years ago from a (now) deceased FOMO race photographer.

I've read many theories over the years, another is they switched to low profile 16" wheels/tires and it disturbed the ground effects air flow altering the handling as Ken attained top speed on the back stretch and approaching the braking zone for turn 9?

I would suspect if anyone had a knowledgeable theory it would have been P Remington.

If any one ever reached a conclusion it's not public knowledge.
