Not sure with the '16 nismo but in the '14 there is also a black bracket riveted to the crash bar. There are two L shaped brackets that face back to back with a nut on the top connecting to what i would call an upper support bar.

I took those nuts off and pulled the L shape pieces to whatever side they were on and then bent the larger black metal piece down to where it is sitting parallel with the crash bar (right behind it). You might actually be able to leave those L pieces on I'm not sure. But you dont have to remove those two plates they are pretty easy to bend so that the end up going straight down. I'd send pics but I didnt take any - you'll know what I'm talking about once you take the bumper off.
