Does downforce lower your car?

[PsuPepperoni]

I noticed that the R10 sits like a monster truck at stock ride height and I was wondering if it's like that so it gets lower at speed.

No... DF doesn't affect ride height...

Theoretically at high speeds with a high downforce setup and a loosely sprung car, the downforce would literally push the car into the ground. Whether or not that's simulated in GT5 is something totally different but by the law that "every action has an equal and opposite reaction" then yes, it technically does.

Maybe not enough to even notice much in real life either though.

In theory yes, but I doubt GT5's aero model is that sophisticated. Maybe GT6's new model will simulate this?

Your correct answer is yes, cars do get pushed closer to the ground at speed in GT5. Ever raced NASCAR and didn't have your ride height high enough and you'll notice in a draft you will start sparking?

You could also take an X1 and just max the downforce in the rear an minimize the front and watched it get pushed to the ground and start sparking.

Or, I have a good visual example: I have a FGT with a STOCK samba bus chassis on it. At 0 mph it sits as high off the ground as a normal samba bus (or higher). Then at about 200mph it's been pushed down to about the normal ride height of a FGT.

To be honest, it's not very complex, and besides coming from downforce, the aero model isn't even involved. It's the suspension model that's important.

If you want to test this, compare a car with and without full ballast in photo mode or something.

I had a good visual photo comparison between a 787B, soft springs at a standstill, then at 400km/h. You couldnt see the ground clearance between the body work and the ground at 400, but it was clear as day at a standstill. Wish I actually remembered what I did with the photos...

Never thought that downforce could lower your car at high speeds.

It does lower your car, hacked cars are a good example of it, if anyone is interested seeing it, send me a fr.

Yep, just simple laws of physics. If you ever take a stock X1 and lower the spring rate a bit and raise the down force all the way up in the rear, it will repeatedly bottom out at high speeds. Makes a pretty loud thud in my sub-woofer every time to.

As mentioned yes. Take any nascar or x1, set your suspension as soft as possible and watch the sparks fly!

Laws of physics don't exist in GT, all that exists is what the programmers put on the disc and dlc. If they don't program something, it isn't there.

Sparking doesn't necessarily indicate the car is lowering due to downforce at speed, it could simply be a ride height issue or a combination of both. Someone would have to take a picture, on level ground of a car at standstill and another at full speed to be able to discern whether this is modelled or not and to what extent.

I did this recently after reading this.

Unfortunately I'm using the app and can't really upload pictures from my phone but I can say that the ride height does lower with more downforce.

I tested this with an Escudo. Maxed the rear ride height, softened the rear springs, maxed the rear downforce.

At no speed, the rear was, well, way off the ground! Obviously.

But at top speed, it was far FAR lower, very close to the ground. This going perfectly level at SSRX.

Then I tested this in GT4 and what do you know? Same result! I guess that this has actually been programmed for a while now and I'm actually quite impressed.

Thanks man.

I know they are programed, but they are based on laws of physics (when I had said "laws of physics" I meant what the programming is trying to replicate).

As KinLM said, that same thing is what I was describing when I was talking about the X1 earlier. Same thing with a lot of cars that have a high top speed and high downforce.

Well done:tup:👍 I like it when someone takes the bull by the horns for actual proof If you could throw up some pics at some point that would be great:tup:

I just got off of work, so within the next hour I can do that, at least if he doesn't beat me to it.

Im pretty sure you'll beat me to it as I'm at school right now.
