In the hands of a capable driver the Z will be fast. But at the same time the margin is too small to assume that the Z will romp over an IS. Don't forget , converible's frames are considerably less stiff equating to lesser handling characteristic. In short if both had equal drivers(is there such a thing?) It would be a close race.
