Hey guys and gals this forum is to help all of you who maybe are not that great at setting up a car in GT6. In my opinion many people struggle with setup because they either do not know how to diagnose and fix the problems. No worries I will cover most if not all of it in this forum. It is also important to point out that I do NOT claim to know everything about setup in GT6 and also struggle with it from time to time. I just want to help with the limited knowledge I do have about tuning in real life and in the game. SO with the Intro and disclaimer out of the way lets get started!

Ok so lets start from the beginning and set some basic vocabulary because for some of you it is hard to tune because you don't know what in the blessed hell camber or tow really is. Here is a list of all of the setup vocabulary you may have trouble with.

Vocab.

Anti-roll Bars- Anti-roll bars help stiffen the suspension during cornering so that the car can turn easier.
Camber Angle- The tilt of the tire towards the center of the car
Dampers- I don't really have a definition for this but I can tell you that dampers are inside the shock and determine the speed at which the shock compresses and decompresses. It's not really important to know what they are as knowing what they do.
Downforce- the downward pressure exerted by the flow of air over the car
Ride Height- The measurement from the flat ground to a set point on the car (usually front and rear bumper or frame rails)
Spring Rate- How hard or easy it is to compress the spring
Toe Angle- the length between the opposite side wheels (LF->RF, LR->RR). Measured by subtracting the length between the back of the tires from the length between the front of the tires.


For now I'm going to exclude transmission and drivetrain tuning vocabulary because we will cover it shortly.

Now that we know the vocabulary lets start by going over the process of tuning. Think of tuning like science where there is always a certain way to do things so that the outcome is correct and can be duplicated.

Here is my recommendation on how you should tune.
1.Analyze
2.Test
3.Asses
4.fix

I use this process when tuning any car because I can keep track of my changes and it is quick and easy.

Step 1: Analyze
Ask questions like:
What type of track am I going to be driving on? Street, Mountainous, Hilly, Flat, Smooth, Banked?
How many turns are there?
How slick is the surface of the track?

Analyzing also helps with learning a new track.

Step 2: Test
before doing any sort of tuning you should drive the track with the base tune the comes on the car when you first buy it. testing also helps correct or prove any assumptions made in analyzing and also gives you a base point for when you go to change anything on the car.

Step 3: Assess
This can be done while testing. take the time to find any flaws your car may have.(That does not mean its defective appearance or sound) This means find out where the car does well or not so great.
Ask questions like:
Is the car loose on entry to corner or does it just want to push straight?
In the center of the turn does the car slide out from the back end or does the front end push towards the outside?
When exiting the corner does the back end kick out when I get on the gas or does the front end just want to push towards the outside wall?

Step 4: fix

Now that you know the problems you can fix them. However, do NOT try to fix them all at one time. take each problem separately and after you make any changes repeat steps 2-4.

Ok so now you know the correct steps to take in tuning your vehicle now you need to know the correct order in which to tune.

Step 1: Transmission
The transmission is probably the most important part of tuning and should always come first. That being said it is also the most complicated. Which is why alot of drivers will take the easy way out and just put the final gear all the way up or all the way down and set the gear ratios at max in the opposite direction of the final gear. Sure this works if you are looking for top speed or acceleration. The flaw with this way of tuning a trans is that it will negatively effect the handling of the car.

Yes, The way your transmission is setup can effect the handling of your car. For this reason I like to use a formula to tune my transmission. Time for another disclaimer. Again I am not saying this is the only "right way to tune" or "the best way" I am just stating that this works for me and may or may not work for you. Anyways here is a link to a thread that tells you the formula and how it works because I'm not that good at explaining it and others are.

Step 2: Drivetrain
Almost as important as the transmission, the drivetrain setup can have a major effect on the handling of your car. The drivetrain is dependant on the driver and is different for every driver. It all depends on what YOU are comfortable with. Personally I like to use the perimeters below because I don't like alot of torque but I still want the acceleration. As for braking it all depends on the car because every car has a different brake package. Ideally you want the car to stop as quick as possible without locking up the wheels so that you can turn in to the corner. Now some locking up is ok as long as the wheels aren't locked up when you turn in but that is all regulated by your brake foot.

Initial Torque: 10-6
Acceleration Sensitivity: 14-11
Braking Sensitivity: 15-40

Step 3: Downforce (Full)
I like to start with full downforce to eliminate this variable while doing suspension tuning. and then once I know my suspension is right I will go back and mess with lowering the downforce. It is important to note that once you have changed the down force from full you will probably have to do some adjusting on your suspension to compensate for the loss of downforce.

Step 4: Suspension
Now you're ready to tune suspension! This part is where the assessing part comes to play because if you don't know what is wrong with your car than you can't fix it. I'll let you in on a little secret of mine. I use this cheat sheet to figure out what to do with my car this guy obviously knows what he is talking about and is one of the reasons I typed this guide in the first place.

By @Trewer_Rath
https://www.gtplanet.net/forum/threads/analysing-setups.149604/

Now this guy doesn't tell you everything but he gives you the basics on what to do and what you need to know when making adjustments.

One such thing he doesn't tell you is which way to go when making adjustments. For example when it says "softer rear anti-roll" how do you know which way to move the slider?

heres a quick guide to help you figure that out

soften suspension stiffness= softer spring rate= higher number
harder suspension stiffness= harder spring rate= lower number
softer damper= lower number
harder damper= higher number
harder anti-roll bar= lower number
softer anti-roll bar= higher number

Well thats about it on tuning I hope this helps! If there is anything that you think I missed, could add or if you have any question feel free to ask.

I can see what you are trying to do and I applaud your attempt but you have left a lot of important bits out unfortunately.

You have stated a few vague directions to which settings you use but not how or why as well as leaving out which car these general settings apply (settings don't transfer perfectly from one car to another). In order to be a useful guide you need to explain how and why things happen so that people can understand how to use them to their advantage.

Not trying to put you off carrying on with this but if you want it to be truly useful then you're going to need to spend a lot more time fleshing things out and be able to give more accurate advice.


Try giving some of the existing guides a read for inspiration

It is also important to point out that I do NOT claim to know everything about setup in GT6 and also struggle with it from time to time. I just want to help with the limited knowledge I do have about tuning in real life and in the game.

I stated that I don't know everything about the setup physics in the game but I do know how to diagnose and fix issues which is what I explain in the OP.

As I also said in the OP the transmission and drivetrain settings I use are what is comfortable to me I said I am just suggesting them as a possible way of tuning but I know full well that others may like other ways of tuning because as I'm sure you know everyone has there own style of driving.

I use this step by step process on every car and it works for me. I'm not actually giving anyone any of my exact setups just suggestions. I don't go into depth because that is not what this thread is about. It's about giving a direction for which beginner level tuners can take using threads like your's.

Also not trying to bash you but your thread is not perfect either it leaves out pretty much everything that mine doesn't while mine leaves out everything that yours doesn't. Thats ok with me as I said I'm not trying to tell people what and how changing spring rates or dampers work because there are already threads that do that.

As for acknowledgements I suppose you are right. I figured if someone clicked on the links they would see that the user who posted them was not me but the one whos name is at the top left corner of the page.

No need to get your back up mate, I'm not saying you are wrong to try to give guidance, all I'm saying is that you are not giving important information that would give your solutions relevance.

You're strangely specific on some bits but vague as smoke on others, you are saying do this and do that but not saying why or how.
The bits you are specific on are solutions to some scenarios but not applicable to all, you don't always start with the transmission and its far from the most dominant tuning aspect in terms of handling, also putting full downforce on a car as a standard practice is never a good idea.
You mention things about track conditions but don't say why this is important or how this could affect things, if the intended reader is a complete beginner then they might not understand why these things are important or how to begin tackling them.
Different cars have different problems for different reasons, explain these bits and what to look out for, that's information others can use. Saying "Find the problem/Fix the problem" is sort of like saying "Find the moon/Touch the moon", there is a big and important gap in the plan that is lacking proper explanation.
 
just pointing out that rollbars stiffness lowers body roll, not understeer, it seems the same but it isn't... i was thinking to do something like you are trying after i printer and self modified all the tuning guides i found around and started tuning for my self pleasure...
 
@azidahaka the reason I said that is because by lowering body roll it can directly effect understeer. The guide that I use to figure out how to fix a problem breaks down issues to oversteer or understeer and tells what to do to fix those problems. The olny thing that I wish @Trewer_Rath had done is tell in which direction to move the sliders like I did in the OP of this thread. It would have made things much simpler because if people don't know which way is stiffer or softer then they could end up going the wrong way. So that s why I put this kind of legend

soften suspension stiffness= softer spring rate= higher number
harder suspension stiffness= harder spring rate= lower number
softer damper= lower number
harder damper= higher number
harder anti-roll bar= lower number
softer anti-roll bar= higher number

Softer spring rate = Higher number??
You might want to fact check that one....

I think you need to do a bit of reading on the basics of mechanical principals and how they are applied to suspension tuning. I'm willing to help mentor you on the basics if you'd like but it is up to you, I feel you'd be much more helpful to others if you took some time to polish your knowledge 👍

yes it does actually because setup perimeters are backwards and I can prove it

Hi, I do not always understand what my tuning is doing and I prefer seeing proof of a method to be able to understand how it works instead of blindly moving the sliders to try and make the car drive better. Could you be so kind as to prove this theory you are presenting?

Oh boy,this is going to get very interesting in 5,4,3,2,1.

Is that why Ghost Salvage Tunes folded? ;)

@DaBomm4 I know from experience on real life cars that a the high the number the harder the spring is to compress, that is the basic principal of SPRING RATE. What GT6 actually has is not infact spring rate but SPRING LOAD RATE the which actually gives you more spring travel with higher numbers. I know I was just like you I thought by lowering the slider that my springs were getting softer. after countless times of watching myself go in the wrong direction and the car getting worse I finally figured out that if I actually increase the number my cars started getting better grip and more weight transfer.

Is this your proof?

So you are saying that if I set my spring rates to the highest number that the body will move around on top of the springs more?
 
why whenever someone tries to make a thread trying to help out there is always some A**HOLE that tries to discredit them seriously I'm trying to do something nice based on what I've learned and know and someone comes along who thinks they know everything there is to know and tells me I'm wrong the proof is my speed on track.

I wouldn't recommend that you set your springs to the highest they will go because there is a point where the car will begin to roll to much and develop a push.

So then you should enter a tune into a FITT challenge to show us this proof that you speak of. We are not getting enough proof to convince us against the way we are currently tuning. If you can explain things more and give testing and proof for it, we would not pursue with so many questions that you think are things trying to discredit you.

Easy way to stop this:
1. Don't claim things that defy what is commonly accepted as true, and then not post proof. No, "it made me faster" is not proof.
2. Don't get defensive when someone asks for proof.
3. Don't act like a holier than thou :censored:hole("I know I was just like you..." oh god why)

Wanna prove your claim? Jack up the ride height, drop the spring rate all the way down and post a replay of it. My money is on that car bobbing around more than a carnival ride.

Izzy - here is my recommendation to you. Less theory, more tunes. I found that my critics got quite when I started posting tunes and including my tuning notes to show my work. Like this... https://www.gtplanet.net/forum/threads/motor-city-tunes-gt6.291066/page-19#post-10033084

Just thinking that this method may work for you too. I have received comment about the tuning notes where people made the same changes then either confirmed that they felt the same or felt that they experienced something different. Might be something worth considering to show how your spring theory works?
 
IMAG0048.jpg

Both cars were set to max ride height and minimum dampers and ARBs. Blue had max spring rate, pink had min. I also have the replays:
001 is Arena max spring rate
002 is Arena min spring rate
003 is SSRX max spring rate(not a full lap, just a little breaking, accelerating, and swerving)
004 is SSRX min spring rate
If you don't want to watch them, here is the summary: max spring rate had less body roll, min could replace your state fair's tilt-a-whirl.

IF (and i say IF) i'm reading it correctly the graph the suspension were almost bottoming up and down at the 0.1 mark?

Some curbs jumping?

i never used the graphs above when trying to tune a car, i think GTP could really make good use of a Telemetry FAQ for it would be an invaluable too for tuners.

Yeah, its hard to miss the curbs with such a big car. I never bother with the graphs either, but in this case its good for showing a general difference in the body motion. I was going to do just the replays, but I don't have a way to record the video and most people wont want to load 'em themselves.
