scrawled the following:

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.

I was also involved in D Prod. My best friend ran TR2's,3,4's. You can
bore out a TR4 and install a Rambler piston and get some serious go power.
;) Was never a real Porshe fan. The first sports car I ever worked on was
a Maserati. Went down hill from there. Aquaintance near where I lived had
a Maserati, and I help him with some brake problems during my teen years.
I was always great mechanically. Grew up in a large machine shop
enviroment. Was going to be a mechanical engineer or geologist. But due to
lifes whims, I ended up an electronic engineer.
