Those testing the car felt that due to the car's weight,none of this lift was an issue for stability.
The prevailing thinking of those times in America also suggested that larger/heavier cars cornered better because the weight kept them planted on the road. This classic thinking is alive and well even today, but that don't make it right - not in the slightest.

Just about everything I've done to my pick-up truck has been to get more down-force without sacrificing mpg's, and that has been my choice.

Anyone thinking it's safe to go 115 mph in a 2-ton muscle car has brass balls and perhaps got a hold of some good recreational drugs in 1969.

I'd do 110 mph on a motorcycle, or 140 mph in an old Porsche 911 before I'd do 115 mph in a 1969 GTO.

A friend of mine had a 1969 GTO back in 1979, pretty thrilling doing 60 mph on a side street, that thrill would soon turn to terror at truly high speeds I'm afraid.

115 mph at driver's discretion to say the very least.
