Nice car Arctic. I actually like the spoiler.... might be a little piece of plastic but it would be interesting to know if it has a serious aerodynamic purpose.
Thanks. Since they stick the same thing on the coupe and convertible, in any trim/engine, and allow customers to delete same, I'm pretty positive it was placed there for marketing/gimmick purposes.
Since you're interested in the 370Z, it has 3 rear spoiler versions. Base has none other than the shape of the rear hatch, the upper trim has a noticeable one, and the Nismo is larger still.
Not a spoiler type of user, but in the 370 I think it needs one and the upper trim sport units with the 19inch RAYS and big brakes seems to suit the overall car.
