top heavy? Maybe has a less than ideal center of gravity height with the tall tires and high oem ride height. Not top heavy by today's standards.
you were right that suspension does help with those 90 mph turns, crazy freeway drivers around here got me up to 94.4 mph and it gets more solid feeling as it goes. Someone else decided to try to pass me on the outside of a 2-1 lane merge in a 90 degree right turn where i was next to the kerb ( in the actual lane perhaps, since it's 1 lane there.) i just held 30 and waited for him to wake up and stomp his brakes and get back behind me where he belonged.
do they rust more than other cars? in what conditions?
