As I understand, one of the few inherently less perfect traits of the 911 is the feeling of wandering lightness in the front at high speed. Apparently it is still noticeable on the latest models. Not that I would know from personal experience..
Must be annoying for the Porsche engineers. Many less expensive and race focused family cars feels more planted at higher speeds.
Well, if you have to have a 250 kg piece of metal hanging out behind the rear wheels....and personally I wouldn´t have any other way.
