The R34 GT-R spoiler

Updated: 29 Nov 2024

Everybody knows the spoiler of the R34 GT-R by how it looks.
But I’m sure not too many know it looks on the inside and how you can change downforce.

It has 4 different settings for the spoilerblade level.

On the top picture you can see the inside of the spoiler, it’s hidden behind the end caps.

Picture two shows the spoiler in the least amount of drag, It might even create lift.

In the third picture you can see the spoilerblade in the most agressive position.

I have no idea how this will affect driving the car as I haven’t driven it since changing the settings.

Hope you guys find this fun/informative to read!

Flat as seen from the rear

And all the way up, drivers behind me can now clearly see the Nismo logo.

Will that fit on my Honda?

That’s nice bit of knowledge! :)

But now one bit of knowledge to you. That thing ain’t a spoiler. It’s a wing. They aren’t the same thing.
Wing=increase downforce
Spoiler=reduce lift and/or drag
Hope you found that information useful :)

Ah, maybe it’s a dutch thing to call them spoilers.
And with spoilers in USA for example they sometimes mean frontbumpers etc.

Thanks for sharing your knowlegde :)

yup air foil is the technical term.

its a dutch thing.

Actually, the difference is a bit more complex.

A spoiler gets the name from its function: it spoils the airflow to reduce lift or even create downforce, or maybe even redirect airflow in a horizontal direction.

A wing (strictly speaking) needs to have an airofoil (aerofoil, for the British) shape to be called a wing. The shape is similar to an aircraft’s wings.

This means that spoilers can produce downforce without being proper wings. Sticking a straight piece of metal at an angle on a car that has 0 lift will create some downforce (the amount depends on the angle and the size of the piece), but because of its shape it cannot be classified as a proper wing.

However, the two terms are usually used interchangeably, because the difference between them is too technical to be important for road cars.

a wing functions like an upside-down planewing, while a spoiler spoils the airflow to reduce lift

simplest way of explaining it

Well thanks for that good bit of knowledge never knew the GT-R’s spoiler is adjustable

Nice, you are from the netherlands too?

Yea

Actually, I believe the stock wing doesn’t have that, but the Nismo wing does. Can’t be certain since I forgot if I read that from Nissan/Nismo or Wikipedia :p

You could be right, you’re making me doubt my knowledge! Thanks haha.

This isn’t just a R34GTR thing, my Evo VI RS2 had a system just like this. Only it had 3 ‘settings’ for the front side and 2 at the back side. And does the R33GTR also have this? Still, would be good to see more of this stuff!

Yes R33s one are slightly adjustable

Sounds like their should be an article on the proper name for auto parts. I’m sure lots of diy mechanics out there have misconceptions on what parts are called(myself most likely being one of them)
