What are these 'Baseline setups' that you speak?

So what? Real teams use telemetry and data to setup their cars, they don't go in blind.

And of course you can feel it while driving, the app just zeroes in on why that is happening (understeer under braking in the example cited).

 

Anyway, baseline setups, some sims out there have really horrible default setups, so basically you create something driveable that doesn't want to kill you, and import to every track.
From that point you start to work on the track specific version.

 

Well, the fact is none of it is going to help you one bit if you can't drive consistent laps in the car to begin with.

 

It basically work like that actually.

Not everybody are into car things & it's sad if you think everyone who didn't know is a retard because of it. Oh wait... It's based on skill as long as people don't know.

 

lol. Not knowing is fine. Saying that knowing is an exploit is the retarded bit. It's hilarious I even had to explain that.

What's sad is the little world you have built for yourself and the behavior that comes with it. I think you need help.

 

The consistency from experience is an exploit as well. Not all driver's have the same amount of experience so the one guy with most experience and skill is exploiting hard!

 

Now lets get back to setting up a car:

Aero balance.
Probably the most important thing in a car that relies on aerodynamics like GT3 GTE LMP and Formula cars.
In GT3 cars there are usually only 2 viable setups, as you can set the slider only to 1 and 0 at the front.
As it doesn't matter when you crash in a training or hotlap session, I start by setting up a oversteering balance. In most GT3 cars this is 1/2 (front splitter/rear wing).
After a short time you will notice that the rear end is very loose especially in fast corners. Then you increase the rear wing by 1 step (1/3) and run again some laps. You do this as long until the rear is as stable as you want it. Don't go too high with the rear tho, as it will create understeer obviously and you can't take corners as fast. The goal is to get a setup that is neither under or oversteering.

 

Correction: More downforce at rear (by changing the AOA of the rear wing) does not reduce grip from the front. The understeer condition is achieved because increased grip at rear would allow even more grip from the front (and higher lateral acceleration). So increasing rear wing does not reduce from the car's maximum lateral acceleration!

The real reason to not run rear wing too high is increased drag.

 

Are you sure this is right?
When i use a gt3 at nords(like the r8) i can get flugplatz without lifting when i use 1/4 settings. But when i max out the rearwing, i can not. If Im just understanding it wrong pls explain

 

Yes it does in high speed corners.

Wrong again. Having more grip at the rear than the front causes the front tires to slide before the rear tires causing the understeer.

Wrong again.

Anything that increases drag decreases not only acceleration, but overall top speed.

 

About the understeer with max rear wing... Isn't that due to the weight imbalance created by the change in the rear wing which can be rectified by readjusting by a faster rear spring rate & maybe few adjustment on the overall damper front & back?

 

When you increase the downforce on the rear, the faster you go, the heavier the back end gets. No matter what you do with springs, that will never, ever change. There will ALWAYS be understeer because the back end will ALWAYS be heavier. Adjusting springs may mitigate it at one end, but not the other. Somewhere, you're going to suffer...greatly.

 

I have found that Stavelot at Spa demonstrates very well that if your rear wing is to high you will get understeer. I have been playing around with the McLaren 650gt3 and at 1front 5rear I was pushing wide at Stavelot went to a 1front 4rear and it was dead on. YMMV

 

You defined understeer but fail to understand that lateral capability of the front axle do not significantly change when adding rear downforce. You guys are talking about car not making corners with increased rear wing, which is caused by a driver error (very easy to steer too much when car understeers, not a balanced car so rear doesn't communicate). In real world everything affects anything and it depends heavily on the mechanical layout of the car how much front grip is lost due to side effect from increased aero load and how it affects the mechanical weight transfer.

All I'm saying is that rear wing adds almost direct force at the rear axle. In comparison, if you stiffened rear anti-roll bar, that would have an direct effect of the lateral capability of the front axle.

Again, lateral acceleration. You're thinking about longitudinal acceleration.

 

I don't know how you can change the suspension so much that it negates understeer from too much rear wing. I tried 3 times going on he R8 over Flugplatz with 1/10 and was everytime at least 15 km/h. And this was definetly NOT caused by drag or driver error.

 

I did some quick math and in case of a gt3 car you are right. Rear wing so inefficient that moving AOA from 3 to 10 doubles the drag and increases rear downforce by 10%. Quickly approximating lever arms and taking the moment of forces at the rear wheel, this 10% at 250kmh+ speeds equals to about 30kg increased downforce at rear and 17kg!! decreased load from front. so effectively increasing car's total downforce by only ~3% (13kg) while adding 25kg of drag in addition to the movement of the aero balance (that you experience at Flugplatz).

Don't trust my numbers though, if you're interested enable developer apps, open the wings-app and test it. You'll get exact result.

 

This isn't a drag racing game. It's a road racing game. You have no point.
