So I was watching a video on the 370gt and the guy said that he loved the four wheel steering. This really confused me as I did not know that the g37 had this. I have a g37s and my question is, do the g37s' have four wheel steering or is it just the skylines that have it?

 

Not found in US models.

 

I always thought it was available but a unicorn option on the early models that no one got

 

I had it on my 07 G35s 6spd Sedan, it was a super rare option. I noticed it on the highway when changing lanes which were definitely a lot crisper. On tight turns, at speed, it made the car a little unpredictable and I had some nasty curb rash as a result.

You know you have it if you see a "4WAS" light when you turn the car go on and then off.

 

Agreed, at least available on the coupe. I think C&D tested an early coupe with 4WAS

 

I have it on my 07s sedan 6mt also. You can feel it in a lane change and fast sweeping turns, like an exit or entrance ramp.
