anyone is welcome to post any other ones they can find that would look nice! thanks!

Why?

was thinking the same thing. mostly see evo's with them, but never a 370. vortex generator, supposedly helps direct more air to the real spoiler but i'd like to see some wind tunnel data to back that up :)

It works in conjunction with a tall rear wing like an Evo. With a smaller spoiler like the Z, it most likely has no benefit.

Neither lol

definitely the shark fin if you decide to get some, those carbon pieces look terrible :ugh:. I don't know, functional or not they MIGHT look okay on the Z. I would have to see it in person or photoshopped to tell.

If I saw that on your car, I'd rip it off.

Tom don't like, leave em for the evos

They wouldn't even really help if you had a large rear wing. The vortex generators are used on an Evo due to how abruptly and sharply their roof breaks into the rear window. It's a muuuuch steeper turn than the Z's, which basically just smoothly goes all the way back. When the roofline breaks like on a sedan, the air over the roof had a hard time sticking to the surface and will only start to flow down near the end of the trunk. Vortex generators create turbulance in the air, which help because turbulent air can follor the sharp turn much better. So by the time it gets to the wing, the air has already dropped down and smoothened out.

But the Z doesn't have this problem. It won't benefit a bit from fins.

i saw the 10 peace kit on a blue 370z and they looked really good, ill try to get a picture up

Exactly. The Evo had this and the STI had the little spoiler over the back window. OEMs have wind tunnels they can use to test things like this and make sure they actually do something. On a Z, its a taped-on piece of Ebay carbon fiber. It's your car, go for it if you like it. Just don't think it will help aerodynamics in any way. It'll probably look pretty odd with the existing roof lines.

For the love of Jesus don't do it.

if you want REAL vortex that have proven results, get this instead:
