So Z1 said they don't have any or Nissan doesn't?
And I have seen plenty of Zenki's wearing Kouki panels from the side skirts back. The reason that bothers me is that the whole thing with the Zenki is the rounded edges....the Kouki is very angular. Those two don't mix on the same car, at least not for the sake of lines flowing from the very front to the very rear. The same reason Kouki wings look terrible without the Kouki bumper, it needs that ledge to offset and provide contrast. The rounded Zenki bumper just can't do that.
