It would seem from what I have read that the cars with the lowest
polar moment are actually the most likely to suffer from TTO, i.e.
911s and MR2s. (BTW, I drive the latter.) I think that the real
problem with these cars is the combination of rear weight bias and low
polar moment. Low polar moment influences how quickly the car spins,
rear weight bias is what makes the car spin once the rear wheels are
unloaded. I remember reading a review of the big block street Mustangs
back in the 70s and the reviewer commented that he couldnt get the
tail out because all the weight was on the front wheels and the car
simply wouldn't rotate, just smoke the rear tires. Just my $.02
