Hi Neil. Good point, I understand the effect on controllability. I can see,
on a short wheel base, car how you would want to slow down the twitchiness!
However, some small coupes and sedans I see the ballast on the floor near
the driver instead of out back under the bumper. I wonder what is going
there? Maybe it is to get the CG substantially ahead of the CP. If you don't
have much room and the trade is CP vs. PM then I guess you have to opt for a
correct CP. -Elon

I think the main point of having a high polar moment of inertia in an LSR
vehicle is to keep the car controllable. A low PM vehicle is great for
autocross and road racing as it can change direction fast. Once you lose it
in a mid-engine car it spins very quickly. This makes it difficult for the
driver to gather it up again
