So after some thought and as much as I liked my sport wing. The Z just looks right with the Nismo wing. After seeing it on danegrey's car I opted for the Siebon cf style wing.
So this thing was a straight forward install. But I dont think my measurements were perfect. The wing sits a tad bit behind. Drilling was fine and holes matched up. Got some 3m tape and fitment was like 8/10. But, I like it.
