Downforce changes what?

[Fe662]

I'm asking myself:What does Downface changes in the car?Any help?

http://en.wikipedia.org/wiki/Downforce

"The same principle that allows an airplane to rise off the ground by creating lift from its wings is used in reverse to apply force that presses the race car against the surface of the track. This effect is referred to as "aerodynamic grip" and is distinguished from "mechanical grip," which is a function of the car mass repartition, tires and suspension"

DownForce is created by air traveling over a car. As the air pushes down on the car, it creates downforce.

This downforce will increase grip, and increase drag. This result is a car that has more lateral grip and more stability at high speeds.

On the downside, a lot of drag will decrease the top speed and high speed acceleration of the car.

Try running down the street holding a square section of cardboard box above your head. Check for results.

Is there really any need to discuss this here when Wikipedia knows everything, even 42? And queue TB with the lock.

Basically to sum up the posters above me, Downforce changes the aerodynamic grip of the car. Best way to really experiance it in action is take a untuned car(preferably one where you can adjust it), do a few laps, then increase the amount of downforce and do a few laps again. You'll immediately notice the amount of grip the car has gained.

It means a lot less braking when going through corners. And of course lower top speed. But cheer up, it`s all about control

I'm still wondering what downface does.

It gets you a virtual slap. How many languages can you speak? Could you go onto a Portuguese* language forum and make a perfect post? 💡 Have some tolerance, people.

* Just a guess. With a PSN of WagnerAlmeida I'm guessing there's Portuguese involved somewhere.

He quite clearly means downforce. Now, carry on with on topic posts.

downforce = drag

lower top speed, lower acceleration

better traction, better handling, better braking

 

[Tower Turn 13]

For specific cars, try La Sarthe to test the effects of downforce. You will clearly see half of this is a df track (porsche curves etc.) and half is a fast/straight section. Take all df off and you will get higher top speed and quicker acceleration on the back straights. Put it on full and you will have better grip through the curves. A lot of the decision making is based on the track. The rest is preference.

Yea I speak Portuguese,but I am from brazil...

Just FYI, while in reality downforce usually, but not always, adds drag to a car, in GT5 the effect is negligible.

Downforce should always be maximized in the game with one exception:

The aero balance of the car is not correct. If with max downforce, the car oversteers and no changes to suspension or LSD fix the issue, you must reduce front downforce. If with max downforce, the car underteers and no changes to suspension or LSD fix the issue, you must reduce rear downforce.

Downforce will
-Improve cornering
-Improve braking
-Improve stability
-Lower top speed and high speed acceleration (in real life)

This.
More downforce=more grip.
More downforce=almost the same speed

it does lower top speed in gt5... average top speed is a whole other matter , as to why some cars have faster lap times with full down force....

Is Downface anything like planking?

Refer to my post above. Now, go and stand in the corner

Agree,

In GT5 the side effects of full DF are almost non existent.
Downforce is basically like an upside down aeroplane, so instead of flying up, the car gets pushed down.

That's worse then people who only read the title.

O.T.
What's this 'reading' you all speak of? I just pick out random phrases and respond vigorously and incoherently until a thread gets locked.

We seem to have quite a few members who have trouble with joined up thinking.

 

[Paul2448]

I makes the car go faster through corners, and slower in a straight line.

For a vast majority of cars, the higher the downforce is better. The only real exception is at Special Stage Route 7, Circuit de la Sarthe, and sometimes Daytona, and sometimes Indy.


But at every other track, more downforce is better.

 

[Exorcet]

More downforce is 100% better at all of those tracks except maybe SS7.

 

[Tower Turn 13]

More downforce is 100% better at all of those tracks except maybe SS7.

I think dialing it down some at Sarthe can make a difference. Hitting higher top speeds seems to be somewhat important on the back straights, which compose about half the track. Especially if you take away the chicanes.

 

[Exorcet]

You'll get maybe 5 mph difference on the straights with a LMP car, but you'll fly through the turns with downforce. In real life you might be right, but GT's downforce is really skewed.

 

[philhiscox]

downforce

this increases the friction between the tires and the road (grip)

friction force = µ x Reaction force

µ = coefficient of friction so this wont change unless tires or road change
Reaction force = the sum of the forces acting on the car so weight + the downforce

constant number multiplied by a larger number (the reaction force) will mean the friction will increase meaning more grip for better / easier cornering, but reduced top speed

 

[Exorcet]

Loss of speed due to downforce comes from drag, not friction. The rolling friction experienced by a car is a very small part of the energy lost to inefficiencies (ie, µ is very very small). The difference in rolling resistance between a high downforce and low downforce state is usually taken to be zero.

Is Downface anything like planking?

Hi, The term "planking" is usually refered to Formula 1 cars that have a plank of wood under the chasis to establish how much wear there is after a race. Too much wear (Too much downforce - bottoming out) will get you in trouble. Now back to the thread, downforce = grip around corners, however you loose speed on the straights. It's a fine balance for each track. IMO camber and toe angles are just as important in tuning your car. Most of my cars are tuned and I like this:- Front camber 2, rear camber 1. Front toe -0.1, rear toe +0.2. Springs about 50%, Sway bars at 7, (udjustable suspension required)... Have fun.

i thought this was a jokey comment like the youtube planking
