I've been playing GT5 and now GT6 and I always enjoyed the tunes posted on the forums.

But I'm wondering how do you start tuning a car. When I have understeer for example i just adjust the ride height. But should you adjust the spring rate as well? It's a bit unclear as to with part of your car you start making adjustments.

Is it like a step by step thing

for example

1ste adjust spring rate
2nd ride height
3rd ...

I'd really like to tune my cars myself on GT6 but I just don't have a clue on how to begin. :confused:
 
start by reading up on what part does. Lowering the car helps with handling by giving it a lower center of gravity. Spring rates and dampers stiffen up the chassis to prevent unnecessary roll and all that. You really just gotta experiment. I'm still trying to make my perfect Supra and AE86 and I've had them since day one.

But yeah usually when you lower a car you need to stiffen up the spring rate or else there won't be much room for the shocks to do their things. Or stiffen up the shocks and vise versa.

I'd say just sit down, read what they do and mess around with it until you feel comfortable driving it.
 
Yes what you say is true, but I have already read everything but it's difficult to know where to start

So for example lowering the car helps by giving it a lower center of gravity; this means your car should be set up as low as possible ok, but too low is also bad or not?
 
No offense to the other tuners on these forums, but this has everything you need to know and get started in the tuning part of GT6.

I have been following Motor City Hami tuning guides since very early on in GT5 and he has never steered me wrong. He is a successful real life racer who completely understands how tuning works both in-game and in real life. I have learned a great deal from him over the years and he is the reason I am a successful tuner in this game today. He does an enormous amount of testing before posting anything so you can be confident that when he does post something, it is pretty much spot on as far as tuning goes. As far as I'm concerned, Hami is it as far as tuning is concerned, there is no other. :)
 
Thanks DolHaus that's a really good guide
No worries, I wrote it with people who are new to tuning in mind so it should be able to give you a place to start. Remember to do plenty of testing -
Pick a track that you know and can lap consistently (within a few seconds of each other)
Remember that you need to get the tires up to heat and work properly(1/2 - 3/4's of a lap generally), the first lap will rarely give you an accurate indication of performance.
Do enough test laps to give you a Peak Lap (fastest) and an Average Lap (add the seconds/milliseconds together and divide by the number of laps)
When test driving, concentrate on the car - How does it feel/What could be improved
Change only one setting at a time, its really easy to get over confident and start changing many things at once and screw up the tune.
Changing only one thing means the cause of improvement or loss can be singled out.
Test after every change, do another 5 laps and look for improvement on both sector and overall lap time.
The key is to be methodical and thorough if you want to make your car the fastest it can be.

There are plenty of guides and theory explanations throughout GTP, lots of the information carries over from GT5 so be sure not to discount anything from older posts.

(note: camber is currently broken it seems, adding (-) camber only seems to remove grip so unless this is your aim, leave it at 0.0)
 
First thing you do when tuning is drive the car at a couple of your favourite tracks and make notes. To do this, I tune the transmission, add all my parts to get to whatever level I'm targeting, set the LSD to some really low settings like 5/10/5. I set toe and camber to 0 and brakes to 5/5. Everything else stock. My reason for doing this is that I want to know how the car drives without the benefit or hinderance of suspension and LSD settings. Now drive it and make notes. Where is it good, where is it weak? How is it on entry, exit, mid-corner? Does it rotate well? How does it absorb the curbs upsetting the suspension?

Only when you know the strengths and weaknesses of a car can you begin tuning.
 
For me ride height, spring rate, camber, gear ratios etc. are just fancy names for understeer/oversteer and acceleration/top speed priority. Yeah you may get some tuning ideas from real life tuning but this is still a "game". Experiment. Know what a part does then finely tune them. I always set the tires and springs first. Less tire grip=softer springs, more tire grip=tighter springs. Set the ride height to center (for now) then set all others to lowest except the gears. I always tune the springs first to give the car the basic characteristic that suits my playing style, then I manually tune the other parts.

Yeah but for example do you start off with stock suspension or the fully customizationable one because the settings are different so the car will handle different

IMO you should start with
1: tires
2: brakes
3: suspension
4: LSD

Or not? By the way downforce also alters your grip so you have to test this before setting up your suspension correct me if i'm wrong..

I just want to know if there's any sort of routine to tuning the settings

I think the most important thing to begin with is to get yourself organised for the tuning process.
There is no way to tune with out having a few blank tuning record sheets that you can download off the GTPlanet site here. So you decide on a car to tune, picking a Front engine Rear drive is the easiest, and then look over the stock settings before you do ANYTHING! Fillout a tuning sheet with the stock settings. This sheet can be used as a reference so that you know how the car was setup by the factory. You will probably not use this stock setting sheet that much, but at the very least you have a starting point.

You have now educated yourself on your car of choice and you can bring the car back to stock settings if you want to, or, just partly back to stock. If you follow this procedure you might notice for instance that when you start adding modifications to the your car, these stock setting may change with the new parts. For instance let's say you purchase the fully customisable supension mod. The ride height may now be different than stock! This, without you changing anything yourself! So you can see that having that stock setting sheet is valuable because the original factory settings could be lost, or difficult to get back to.

Start a new setting sheet for the tuning of the car now, and set the stock car settings aside for reference.

One of the first things I look at is how much the car weighs. If it between 1200 kg and 1400 kg then it is OK to start tuning as is. If not, I use the weight reduction feature first to get it into the ball park. Less weight is always better. A light car will accelerate faster, stop faster, and go around corners faster. Tire wear will also be less on a lighter car than a heavier car. Keep in mind that weight reduction wil cause the PP to go higher, a worthwhile penalty if the car is heavy, like a Bimmer or Jaguar. If your intent is to soup this car to the max, then the weight reduction penalty in PP in addition to your other mods can add up to a very high PP at the end of your tuning, so much so that you can put the car into a PP that is in the realm of race cars. This could make it unuseable in some lower classes.

One of the nice features of GT-6, is that the mods are mostly reversible, so you could remove tuning modifications for instance if you paint yourself into a PP corner. I will sometimes soup up a car to the max, and then if I want to put it into a lower class race, I just remove the turbocharger or supercharger or the headers, etc until I get it down to the required PP.

I noticed that you were attracted to lowering the car to the max in an earlier post. Be aware that the car designer set the car up to be able to cope with TOPES (speedbumps) in Mexico with a smooth ride and lots of travel for potholes and other bumps. So if you lower a car from the stock settings, then you will have to compensate by adding stiffer springs. Otherwise the car will "bottom out" and then spin out as a result of having no travel left in the supension. So tracks like La Sarthe and Nurburgring (Nordschliefe) are quite bumpy, spending time as normal roads. For these tracks most tuners will have a special supension tune with softer springs, more travel and higher ride height to accomodate the bumps at 200 mph.

Some of the better tuners will actually raise the ride height of some of the higher performance cars, so don't think that "slamming " a car is a requirement for speed in all cars. That said, lowering the ride height usually helps, but it's a good thing to leave a little remaining, so that front to rear ride height tuning is still available, after generally lowering the car.

The tuning sheet can be followed generally from top to bottom if you are wondering where to start, and you will notice "Ride Height" is at the top of the page. Most important, is to do a lot of reading first. There is so much to learn, and one change affects another so, patience is required.

Finding your test track of choice is very important. I keep a notebook and log my times around different tracks in different cars. If you get really familiar with one simple track first like say, Tsukuba, then you will build an experience base to test on when you are tuning your first car. You could start with the totally stock car and work from that as you modify. You must do at least 3 laps after each tuning change, and preferably 5 laps which is only 5 or so minutes on Tsukuba. Work on consistency in your times with a known car so that all your times are within 2 or 3 seconds on a 5 lap session. You need this base consistency to know whether your tuning changes have made a difference, that's why it's good to run the car stock first, with the tires that you want to tune on, for maybe 20 or 25 laps, and record the average time. After a while you will find yourself lapping within 1 second on a short track like Tsukuba, and then you can reliably find gains or losses from your tuning modifications.

This is a personal opinion, but I will say that my consistency really improved with the purchase of a Logitec G-27 wheel and pedal set. Now, I would never go back the dinky little controller that came with the PS3, I found it like trying to fly an airplane with the tiller of a sailing dinghy. The control available with a wheel is like 100% better and my driving and lap times improved amazingly. The wheel also provides feel feedback. If I am driving a Porche, I can feel the heavy ass-end in the corners and especially braking in the corners! Every car has it's own feel with the wheel and to me that makes the game a simulator.
Happy Tuning!

You start with the custom suspension because that's the one you are going to tune. Set camber and toe to Zero, LSD as I mentioned above etc. The purpose of that is to eliminate as many variables as possible so you can initially focus on the suspension. Everything else follows from that. I don't consider tires as a variable part of tuning. I pick a tire and tune to the tire, I never change tires to suit the car.

I would swap LSD and tires on your list. Transmission is also a factor but usually the last thing I touch. I usually don't even add it on until I'm happy with the handling.

As @Johnnypenso said, add all your parts first to get to the power/weight or PP you are targeting. Then drive it on a track you know well with base settings (as described above) until you know "hey, I'm understeering in this corner every lap" and "I wish it would change direction faster here". Only then proceed to change stuff around to try to dial it in. Try to turn off all the aids you can so they don't compensate for anything.

One tip taught to me by @CyKosis1973 is to tune on tires one or two steps harder than you plan to use. It really helps keep your tires from covering up any flaws in your tuning. 👍
 
For me I just read what each part did and how it would effect the handling from gt4 and over time I've just learn't how to tune, I've won most golds even the vettal challenge I've gold it all, gt5 I learn't alot just by trial and error so when it
came to gt6 I'm having a lot of fun cause taking a corner at hi speed is a good feeling specially the mount, nurburgring and appricot hill.
