I recall reading these explanations, but no longer recall the details.
I don't
recall that it was called "jacking", though. My friend didn't call it
that, if
I recall.

I dare you to find it when googling "car jacking".

Anyone involved with sports car racing in the '60s knew it as jacking. If
you talk to someone who claims to have been there and who doesn't know
immediately what you mean by "jacking," in reference to Corvairs, VW's,
Porsches, Formula V's, Triumph Spitfires, or even pre-'64 Pontiac
Tempests g, then he wasn't really there.

Might have been a regional term. I raced San Francisco Region SCCA and do
not recall any discussions of "jacking".

Well, you were racing Corvettes. We didn't talk much to the guys who raced
above DP. d8-)

Seriously, if you weren't racing against Spitfires, or if you weren't
involved with FV, it probably wouldn't have come up. There were few John
Fitch Corvairs (like mine) on race tracks. But those of us who raced in the
smaller classes were well aware of it.

Porsches didn't have much of an issue with it because their weight biases
and suspension wasn't prone to jacking. The forces preferentially favored
compression of the outside springs, so they didn't build up much jacking
force. You could jack a street-stock Speedster, but by the time they got to
a race track they had negative-camber springs and they were strapped down
with stabilizer bars or a Z-bar on the rear, and Koni shocks, until they
felt like go-carts. The best way for a young tyro to keep from killing
himself with a Speedster was to tie the suspension down hard, until it would
hardly move.
