Rear Spoilers

[galconn]

From a purely aerodynamics perspective the shape of the vehicle generally reflects the shape of an aircraft wing, that is flat on the bottom and curved on top from front to rear end. For an aircraft wing this shape generates uplift as the velocity of the air passing over the curved section of the wing increases the wind velocity resulting in decreased pressure over the top of the wing thus creating a pressure differential between the underside of the wing and the upper wing. We now have lift off. I would therefore suggest that the reason for the large front air dam and rear spoiler in racing machines is to counter the effect of uplift at speeds greater than say 160 KMPH.

It wont make any noticeable difference getting rid of it.

Anyone with knowledge of aerodynamics would look at it and half a second later tell you that.

I would be surprised if much thought went into its design from an aerodynamic point of view - its there for looks NOT downforce.

In fact Id put money on the fact it may even slow down the car way more than any potential top speed downforce on the rear wheels.

How about this: rip it off, and if you happen to be doing a bunch of 200kmh+ runs in your car, stick 2 x 2 litre bottles of milk in the boot to make up for the tiny amount of downforce you will be missing....

I doubt it would do much at all for down force. How many cars do you see at the drags without spoilers? Take it off phil, you won't notice a difference with down force imo. my be is they are purley aesthetic.

how about like the f6 or gt or gtp spoiler. do they do anything or there the same as a t, and there for the looks.

A good use for the wing is 2 see how far u are from hitting another car or a wall when reversing

I don't even bother looking out the back, I just wait for a *dunk* from the highly sophisticated reverse sensing tow bar

I think the only rear spoiler that actualy provided any down force on a modern falcon was the AU XR series Biplane spoiler, and even that was marginal.

As a few people have pointed out without the spoiler there is no way to tell where the end of the car is,drove and Xt hire car and found it very

hard to gauge the distance when reversing so I think if you better have reversing sensors if you are going to take the spoiler off other wise touch parking is the order of the day.

Rear spolier does nothing but look good..... Speaking of looking good, any one got a V8 Supercar spolier lying around. The manufacturer in Qld ... Carbon Composities want 5 grand foe one.... ouch!!

Think that would look good on my car though

Would rather hear from people that KNOW rather than opinions from those that are just guessing.

Jet, see above.

teach me to read the whole post..

Nah you didnt offend me its cool.

I just got pissed at my own bootlid and thought I would take it out on someone else. just kiding. Ford overtightened my spoiler so now the panel is bent under the legs and im a bit pissed that I cant remove it and now I have to get a new one.

Cheers

mine is the same...

all bent and sh*tty where the legs sit right??

rekon we could hit up ford warramty for something like this?

no chance I'd bet..

Given that you can't notice it when the wing is on, you haven't got a chance of a warranty claim and if I was Mr Ford, I would knock back any warranty claim also.

I'm trying to find an article in Motor of the development of the EL GT from a few years ago. It had a few pages of the testing done on the rear wing to provide downforce, they even had the different wings put on Glenn Setons V8 SC to test them at high speeds. This may give some insight into how much difference a wing can make on a road car, so when I find it I'll post the details.
