i have 4WAS on m fully loaded G37S and I love it. I can feel the difference...i dont make crazy lane changes yet so i cant vouch for that... but i did take a couple of exit ramps with speed limit signs for 35 MPH at about 70 MPh and the car stuck to the road great with just slight squeling...I was very impressed...If you are a Nissan drifter by spirit and want to fishtail and correct your sharp turns the way a RWD is meant to be - then dont opt for the 4WAS...If you don't mind the extra control and want a higher tolerance of control before your car begins to swing out a bit then stick with the 4WAS....thats my opinion....I love it.....Im all about stickin to the road....to be quite honest i wouldnt even think of drifting much on street...just track....I wish we could turn off 4WAS....lol can we?

On a race track, you need the car/bike whatever you're on to be predictable when you are charging into turns and making transitions. It's also for the safety of your fellow racers. 4 wheel steering makes things a bit more sensitive during extreme driving conditions. It is great for daily driving (lane changes, on and off ramps, u-turns). I would not want it on a race car, it feels too twitchy during aggressive driving. Some may prefer it for racing, but I like the more linear feel

WHAT! Can we get any confirmation on that? 300#s for active steer is a no no for me. Im not adding that much weight for that option. I just cant believe this is right for a few sensors and tortion bars.

Jusr read somebody wrote 120#'s. Sounds more like it.

Here is one thing I do not like about 4was. It requires less effort to turn the wheel, but once you (ever so slightly) reduce the steering input mid-corner, the thing wants to run wide

The sport model w/o 4WAS has plentiful traction, able to take "35mph at 70mph" + without sliding or squealing. I don't think it is valid to say the 4WAS improves the car because it can corner without leaning (the non-4WAS corners without leaning as well) or because the car goes through corners quickly (the non-4WAS goes through corners quickly too).
You need some good solid back-to-back comparisons to really know. For example, I don't think the system is even active at parking speeds so any advantage in parking is solely in the driver's mind...

I know the adaptive headlights dont turn at parking speeds, but I would think the 4WAS would work at all speeds, normally people slow down to 10 mph or so when you turn.

According to the service manual, at low speeds (it does not specify a mph/kph) the only thing the 4WAS system is doing is varying the steering ratio at the front (not steering the rear tires). This has the effect of multiplying your steering inputs at low speeds and reducing them as the speed increases.
So if you slow down for a corner while holding the steering at the same position, the car will want to steer more as you lose speed and steer less as you gain speed.
The service manual says that in middle and high speed driving the rear tires can be steered midly by the system in order to approximate the desired direction change.
All of this points to unpredictable response to the steering input by the driver.
In any case, while parking all you are getting is a more aggressive steering gear ratio at the front.
I'm not a big fan of this system

I'm intriqued by the 4WAS because my first new car was a 1992 240SX and it had Super HICAS, and it was a sweet handling (but slow) ride. I think the 4WAS costs too much though and would worry that there's more stuff to go wrong.

4 PROBLEMS:
1) MONEY $1300!
2) USE, AVERAGE PERSON WONT BENEFIT
3) REPAIRS AFTER 60k, I bet it would be a expensive technology to FIX or REPAIR, And Like Kenny (Da Mayor) Said You need Wheel Alignments and who knows what else after a while
4) Higher WEIGHT Takes away Performance
