The handling will be better.
On slippery surfaces, the self-centering effect is obvious, the rear end just returns by itself on the path

It is less noticeable on RCP or carpet, even through it will be active. You just "feel" that your car is more stable than the others
On this
video, my Murcielago has the X-speed, giro and the rear tires are foam.
I could give full throttle on this carpet and it would stay on line, unlike the other cars.
I paid 3400y for the giro direct from Japan last year. No idea of the price now sorry.
