rear wings useless?

[col2560]

does the rear wing actually do anything on the fto? or is it just for looks? seems to me that its of no use on a front wheel drive car, maybe im wrong.

[aza013]

it is only for looks when you are on the streets is it only really starts working at speeds over 140+kph.
and it helps on the track but then by saying that it may be a diferent story with the gpx wing

+add to car aesthetics
+improves downforce while cornering at high speed
+Standard issue for all sports car

-reduce rear view visability
-increase weight

wings works for all cars of all drives. theres only superbly designed wings and those for show.

[I8A4RE]

Agree with mostly what has been said above. On the street a wing is totally useless, unless you travel a very high speeds.


It has nothing to do whether the car is FWD, RWD or AWD. It is about aerodynamics which the drive train plays no part.

I believe the factory wing, even in a racing situation, would have an absolute minimal or no advantage what so ever. It is majoritly for aesthetics only.

REALLY!!!!! Nothing in between eh?...........Bullshit

Well, no i'm not really sure the wings do anything on the street.
Although i'm sure on the freeway doing 120 if you hit a puddle and the rear end lets loose, the wing will help atleast a small bit to keep it from spinning or something.

..Had a mate who used to drive a boosted TT Supra with the standard wing, and going about 180 (disclaimer - "on the track") when taking corners, you can actually feel the wing helping the back get some grip.

Wings do actually do something, but not really much under above freeway speeds (take, for example, the Porsche Carrera GT - wing only lifts up at over 130km/h).

Plus, they look damn cool (especially the vR one).

#1 which track or road is your friend taking corners at 180? lol
#2 the FTO GPX spoiler is too low
#3 the fto GPX spolier is not angled at all
#4 I doubt the GPvR is much better, although it appears to be.

The function is for both downforce and stability under braking...but I must say most of them are a toss and def. a toss at normal speeds

However when i added my GTR spoler added about 0.5s down the quarter mile...a few other poeple have had similar results..also playing with my GTR wing angle produced suprisingly different results on race meets.

Eastern creek & maybe this road [33.193174, 151.506232]
That road is wicked. It has massive sized hills

#4 I doubt the GPvR is much better, although it appears to be.

But..aza said so

[aza013]

yes on the track you can see it flexing down at speed.

[col2560]

i can understand that down force is good if you have rear wheel drive. down force = better traction. maybe the front spoiler works the same way on a front wheel drive car.

[vipfto]

I can say with my fto that at high speed 150- 200ish (private roads of course) that car was noticably more stable both straight line and mild degree high speed cornering with wing on. When I removed it and did same thing (same private road) could certainly notice the difference less stable all round.
And no I had not changed any other settings in any way

I get a bit out of the VS wing, especially when it set on the highest level, but yeah only at speed. The last corner at the end of the straight at Oran park (GP circuit) is a 160kmh corner, can feel the ass being quite squat.

160kph corner! sure want to try it out sometime!

[xSlurpee]

Wow ... 160kmh
i skid the sh*ts doing a corner at 80kmhs and nearly hit onto the curb (not a curver its turning into new street)

Ha ha noob you will get better with more experience

Theoretically they delay separation of airflow so it becomes turbulent well behind the car which makes it run more efficiently because of reduced drag, as well as creating down force. If you take a van on a dusty road it will have dust all over the back of it because the air becomes turbulent as soon as it passes around it.

Practically they do f**k all lol

Hi guys, thought i'll add my 2 cents worth.

I did my thesis on aerodynamics on V8 supercars (Ford). the wing is pretty much something to add to the "fierceness" and looks of the car at speeds below 150km/h. above that speed, you start to notice the car feels slightly more stable. the size of the wing and the angle of attack (AOA) can increase downforce up to 200N or more. that's why the V8 supercars have such large wings.

Also, they have body kits that help channel the air to the rear wing. raising the AOA too high can end up stalling the airflow, resulting in your wing being totally useless. a wing relies on Benoulli's effect, much like an aerofoil of an airplane wing. only that it works in reverse.

in actual fact, the underbody of the car plays a more critical role in your aerodynamics. putting a rear diffuser makes more sense as diffusers work even in low speeds of 30km/h. therefore making more sense for street use. unfortunately, it is hard to channel the airflow under the car to the diffuser because of all the obstructions such as muffler and piping, fuel tank, etc...

also, ground effects play a part. you can increase front grip by lowering your car and having a front spiltter/diffuser. unfortunately, it comes at a cost of drivability and sydney roads. also, there is an optimum height to set the height of the car. too high or too low will actually decrease the aerodynamic grip.

in my opinion, in everyday street driving, and speed limits of 110km/h, you can remove your rear wing to save weight. to improve aerodynamic grip, put a front spiltter, rear diffuser (get a proper bodykit that have vents for the tyres) and you should notice an extra 100-200N of downforce (estimated)

if some one can provide me with a CAD model of the car, i can run a 2D and 3D CFD simulation and be able to tell you how much downforce you are adding to the car by changing ride height, AOA of the wing and adding diffusers and spiltters.

hmm... think i made it sound a little too technical. sorry if i bored most of you...

[vipfto]

I reckon thats well put mate and pretty much sums it up rather well

Bad rubber they're like under 50% thread left

Just a question, at the tracks ... is it likely to take a corner too quickly and full roll your car? and what if your close to another car and accidently bump each other ... do they happen often?

Just a question, at the tracks ... is it likely to take a corner too quickly and full roll your car? and what if your close to another car and accidently bump each other ... do they happen often?

it can hapen but you have to hit somthing ie pothole or roll a rim under the car well lots of factores can make you roll
as for bumping another car yep it can and dose hapen but a lot of the time you keep a good space apart so its all good.

the best track to get on first I would say is wakfield park big open track
if you stuff up you just hit the grass or itty litter.

[KJ_bob]

200N... like having a five year old sit on the back of your car as u corner?
