it didn't work out for GM when they added it to the GMC truck. GM dropped it after no one felt it was worth the extra $$$$$$.
The Porsche is a little bit different than that one for sure.
The GT3 guys have already started to complain about it and they haven't even driven the car yet. (sounds familiar)
Most likely, its going to be a very fast lapping and agile car car because of it. But people on here would say its just another thing to mess up and they'd rather have manual cranks and drum brakes.
When I started with Kerbeck almost 20 years ago (next month) I worked at our Mitsubishi store. Mitsu used to sell a Galant VR-4 (sedan) and the 3000 GT VR-4 (sports car). Both offered AWS and most people who drove both styles of cars didn't care for it. It added much weight and expense to the car an many people didn't see the need.
Porsche buyers tend to like things like this and AWD but Corvette owners usually think that they are unnecessary. I guess it's just a matter of opinion but my opinion is no thanks!
All wheel steering has both benefits and concerns. Prior implementation have been less than stellar. I expect this Porsche version to be better. Will the benefits outweigh the concerns, and cost? I look forward to the early and long term reports. I am not going to hammer or praise Porsche for including it without some tests to support said hammering or praising.
I am sure it will require some getting experience to get the most out of it.
I wonder about failure modes when new technologies come out. What happens in failure mode?

They don't like this either. At least the hardcore track guys.

How will it affect tire wear? Evasive maneuvers?
The other problem is that as soon as you start applying power to your turning wheels you have a potential penalty on grip.

Normally the maximum steering angle is a few degrees. On the Porsche it will be 1.5 degrees. So the impact on the friction circle is not that great. It can also reduce slip angle.
It does effect overall handling and how you drive. On some systems it goes one way at low speeds and another at high speeds. So what happens changes based on where you are on the track or road.
The Corvette rear suspension is nearly set up for it already, with a single spherical joint at the outer end of both control arms and a little radius rod that controls the toe. Replace the radius rod base with an actuator gizmo and you're off to the races.
i had this on my 3000gt Vr-4 as dave@kerbeck said and I didn't really notice a difference having it, for the amount of weight added the benefit wasn't as good.
Z32 300zx guys hated it too... Anyone who tracked their turbo Z32s generally swapped out the rear cradle with the NA version that didn't have HICAS (all wheel steering).
Garbage and unneeded when you have a good turning radius.
Should have been 3000 lbs...
Should have have had DCT...
Should have had AWD...
Should have had 500hp...
Should have had round taillights....
Shouldn't have been a Stingray...
Now it needs AWS?
