Help me settle an argument.

[xt6wagon]

I would agree with this. While the track packs spoiler is larger than the tech pack I can't imagine you would notice too much of a difference between the two. It's just not big enough. Now, the R spoiler on the other hand looks like it produces some decent down force.

No, the track spoiler is pretty serious. At 60+ mph even small differences can make a serious difference in handling. Double so as you transition from lift to downforce for each end of the car.

'Downforce doesn't matter too much when you're in limp mode'

With this I guarantee winning the argument...

I don't know that I would consider that small spoiler serious. Based on my track experience that small of a spoiler would offer "something" but not a big difference IMO.

This is on the other hand is a down force wing that you would truly notice.

Man there's a lot of skullfxckig that goes on here. No way you tell the diff between them though I'm sure the taller the spoiler, the more downforce you get but both of them are for looks. Let's not kid ourselves. I've got a big fat gstream wing on my car and I can't tell the difference if its pointed up, down, or sideways and I run in the front of the all mustang class. Just drive it.

For looks? you are kidding your self. LOL

Yea, I don't buy that for a second either. Gstream with an updated front splitter made a tone of difference for me

Spoilers and wings are two different things. https://www.quora.com/How-much-down...ugh-to-make-a-positive-impact-on-acceleration

To summarize:
Both wings and spoilers reduce up-lift at the tail of the vehicle, but use different mechanisms.
Wings are airfoils designed to directly deflect air upwards and thus push the rear of the vehicle down. They generally add quite a bit of drag.
Spoilers are barricades to undesirable flows, and thus are able to reshape airflow streams around the vehicle. This can help keep the rear of the vehicle down and decrease drag by changing the effective vehicle shape.
You need computational fluid dynamics and/or wind tunnel testing to quantify spoiler/wing performance.
Neither have any positive impact whatsoever on straight-line low-speed acceleration. Both are primarily intended to improve stability and cornering at high speeds.

I've stuck my hand out of the car window at 60 and noticed the amount of force the air will exert on it. The track pack spoiler is a lot bigger than my hand. 1.5 tons of down force? No, but still noticeable.

The R wing would be preferred, but too many $$ for me.

I am aware of the difference. The point I was making was simply that the track spoiler is not that "serious" IMO. A wing is serious.

Yes, they are for looks. This isn't a race car and you won't know the difference between them guaranteed.

Ford engineers spent huge amounts of time in the wind tunnel and
on the track tuning this car, It makes a big difference.
How much some notices it, is a whole different conversation.

 

[RadBOSS]

You'll never notice the difference. Probably won't even matter for lap times for 99% of the drivers.

Maybe, but considering the specification of the whole vehicle and its target (Porshe GT3) , it's functional and they did their homework to optimize it. This is a race car in disguise w/o a lot of useless glitzy add ons. The non-R only gets a little deck lid spoiler, which is probably functional as well by helping break up the laminar flow from over the roof, rear window and deck lid to create turbulent flow behind the car and reduce drag.


As far as the argument bigger is better, keep in mind that with more down force (negative lift) comes more drag and more shift of load off the front wheels to the rear which might remind you of increased understeer. There also is a point of diminishing returns.

Since this topic circles around fluid dynamics and aerodynamics, a calculation could be made to determine how much "impact" the track pack spoiler has.

Now before i post anymore i preface this by saying in terms of giving absolute numbers here, the numbers generated won't be accurate as there will be some assumptions built in, but i what i think it will give you is a general order of magnitude in comparison the benefits of the track pack spoiler to the base model spoiler (or even the R spoiler if you so desire).

F = 1/2 * A * cd* p * v^2

This is the calculation for aerodynamic forces. In the calculation:
F= Force

A = area that force is applied to. This is not the total area of the wing, but the total visible area of the wing when viewed head on because it will be on an angle

cd = drag coefficient (for sake of this argument would calculate R spoiler with 0.04 for streamlined body and for track/base 0.09 for streamlined half-body

p=mass density of fluid at a given temperature (assume 20 degrees celsius and this would be 1.204, but you could do any temp, i would just keep constant across the spoiler designs)

v = velocity or speed since many of us lack direction

I would do the calculations myself but since my car is on order i don't have a track pack to measure.

Hope this helps!

I thought the argument was between the wifey

I'm sure the taller the spoiler, the more downforce you get but both of them are for looks.

Taller does not mean better. Positioning the wing in the right airstream coming off the car or not even in the airstream is what matters. It will depend from car to car and how the car's channeling air around itself.
