I only can recommend the integrated active steering !!!
having driven all possible suspension variations before ordering my GT (and not having the urgent need of an x-drive :-)) it turned out that for a car with 2 metric tons and 5 meters on your ass, THIS makes it cornering like a Go-kart.
It drives like a much lighter and shorter car and helps really parking that leviathan in spots you would not be able to do so without that feature.
so, go for it !
