Default hI aLL! what lateral g-force can old cars achieve?

Depending on the type of tyres, 0.7g really pulls it up. At 0.75g, with
balanced slip angles, you're into a 4 wheel slide. Look into slip angles
for answers to your question. The tyre is, in most instances, the
primary determinant. The cornering force developed by a tyre in any
scenario depends on slip angle, load, inflation pressure, camber angle,
drive forces and braking forces.

Modern cars have very much improved tyres and suspension handling
dynamics but I very much doubt you'll be getting 0.9g with *any* modern
vanilla sedan because - physics.
