ya it's for a 370z
That's for a 370Z correct?
Just a thought:
The bumper on the NSX doesn't have cut lines vertically that would support such a piece. To connect the center opening plus the two smaller side openings would look funky. If there was a definitive cut line that a CF piece could fit into, it might work better.
I'm not sure how this would add a performance benefit. The piece I Photoshoped couldn't go back that far anways. There's bumper and frame supports behind there. I wonder how it would look with an NSX-R vented hood. It could possibly funnel air through the nose and out the hood vent giving added downforce stability at higher speeds.
Who knows
