You should visit Rizz's Link page for all kinds of z32 info. https://www.zdriver.com/forum/showthread.php?t=8434
Yep, HICAS is a standard feature for TT's. Many people quickly disable it for drifting among other things. Personally, I enjoy the handling. Here is some more info cut from one of rizz's links.

HICAS is Nissan's name for the 4 wheel steering system that is standard on the Twin Turbos. Unlike other manufacturer's implementations of 4 wheel steering, the Hicas system turns the rear wheels a very small amount (+/- 2 degrees or so) at the max. This sounds insignificant, but think about how badly most cars steer when their alignment is off a fraction of a degree. The hicas system has 3 modes, based on how fast you're travelling. It is turned off at speeds below 30 mph, so don't expect it to help you park. At some speeds, the system angles the rear wheels in the same direction as your front ones. At other speeds, the rear wheels turn in the opposite direction. Wacky stuff. No one really knows how much this helps the handling of the car.

Most z32 guys eliminate it after a few mods anyway, and the fact that it sounds very expensive. Don't think its a good idea, since there's too many parts and electronics involved!
