a beautifully designed car. The car being n/a or tt is irrelevant imo. Speeds above 85mph are the only time a functional wing is useful.
BTW, I have never noticed any stability issues @ triple digit speeds. Again this points to the down force/aerodynamics of the car.
Comes down to preference, I prefer the wingless Z32 by far. If I had to have a wing though it would be stock or an exact fiberglass copy of the "90-"93 wing.
