When were tyre walls, and ‘Armco style’ barriers introduced?

I'm not sure when tyre walls were introduced, but Armco appeared in the late 1960s.

What now seems incredible is that many drivers racing at club level at the time didn't want Armco to be used. My dad was one of them, his argument being that if a circuit was lined with solid Armco, most crashes would almost certainly cause significant damage to the car, whereas prior to Armco, grass banks and suchlike were often less harmful. Quite an ironic argument really, given that he'd fitted full race harnesses in the back of his road car for us children to use!

Great replies that I really appreciate. Thanks for posting the photos ... terrific. Good racing. Keith.

I remember rows of catching fences being placed at Zandvoort in the late seventies. It was not a succesfull safety mesure, the cars just flew through them at frontal impact.

Maybe that was due to their inappropriate placing? I suspect that like barriers they may have only really been intended to suppress glancing blows; unlike tyre walls that can better sustain more direct impact.

I thought the much hated catch fences were at Zandvoort to slow the car down if it was about to either torpedo into or launch skyward after hitting the sand dunes lining the track.

Absolute nightmare if the car got tangled in them, trapping the driver. Wasnt there an incident where a support pole injured a driver during an off?
