Really? I searched the sunline racing website, and I think the mount for the "370z 3D GT Wing type ZC" is different in that picture.
I like how the ones in the Japanese GT picture sits a lot higher and has holes between the mount like the "3D GT Wing type Z for Nissan 370Z"
But this one's bottom bracket which sits on the trunk doesn't mount on the edge.
It looks so much better when it sits on the edge and angles back like this one.
