Drift Settings Journal: Volume 2 - '03 Nismo Fairlady Z Z-Tune (Z33)

Welcome to the Drift Settings Journal.

Here we will thoroughly examine the handling characteristics of various cars in Gran Turismo 4 with the primary focus of the discussion set on their potential as a drift machine. The discussion will remain open for as long as people wish to add input, but a new subject car will be selected on a bi-weekly basis based on the results of a nomination thread.

I don't intend to impose a heavy structure on the conversation. Basically, you're open to post any observations, feedback, or settings for the car that you wish (provided that it is constructive and drift related). Drift it how you want, where you want and let us know your thoughts and about your tuning process and tactics.

I would like for this discussion to be a way of discovering new tuning methods and styles from others. Hopefully it will also become a place to openly talk about drift related handling problems of the current topic car and learn how others have compensated for such short-comings.

If you have any suggestions with regard to how this idea may be made more succesful, please PM them to me.


The subject car for this volume as selected by the forum in the nomination thread is:
Subject Car: '03 Nismo Fairlady Z Z-Tune (Z33)

• May be purchased from Nissan Dealership Tune Shop (150 000 Cr.).

Let the drift settings discussion begin.

 

[G-T-4-Fan]

This thing is damn hard.....the spring settings are VERY stiff.....
I'm kinda curious if someone finds good drift settings for it....

 

[ekmatt9]

...I just hope if some one brings the Spring Rates down...That the car won't be as bouncy...I'll work on this car tonight.

My settings haven't been much of a problem for me. I think it'd be a good base for people wanting to start their own personal settings.

 

[Ske]

My main gripe with this car is that it doesn't seem to wanna go sideways... I'm not sure if the front keeps washing out if it's the rear that's too grippy. I tried grip racing it, and actually found it to be quite tight... I was expecting it to grip beautifully, but it kept wanting to go straight. I thought this car was supposed to be ultra-neutral IRL.. sort of like how the new Skyline feels, I guess.

I guess the main problem areas are:
a) Getting the front to stick mid drift
b) Keeping the rear NOT sticking mid drift

It could be more eager to initiate with too, but it's doable.. the main problem is that everything I do seems to make it want to return to the straight path, so there's a lot flooring it and adjusting the steering involved. It's not an easy car at all, I CAN drift it, but it hurts...

From my experiences, soft rear didn't work too well on this car. It seems to behave best with pretty neutral springs or maybe even stiffer rear, as the emphasis could be on keeping the car out once you've started drifting... and that's as far as my tuning experience with it goes. I'll sit down and have a little talk with it today and see what I can find out

I'll agree that it could be made easier to initiate drift with... but I'm not onbaord with the second problem area you picked out (not to say that it's not true though).

I was testing at Deep Forest using the DS2 with stock car settings and N2's (had racing suspension equipped, but no changes yet). I saw someone complain about bounciness, so I picked the bumpiest course that is unlocked on my drift game.
And yes, it is a very rough riding car.

Coming over crests the rear would kick out, and te same is true for a quick ebrake stab - actually, that worked really well. Once the rear was out that 390hp had no problem keeping it there, for me anyways.

I do agree that more front grip in mid-drift would be useful.

I think my first step will be to soften the bound and rebound slightly. Raise the ride height from 65 to 75 or 80, and soften the springs.
I'm hoping that will take some of the roughness out of the car. It also raises the COG meaning greater and more drastic lateral weight transfer.
Maybe it'll work, maybe it won't. I'll let the rest of you know either way.

 

[Ske]

I think the 2 are linked though.. less front grip means understeer, means that the car straightens out, and the rear grips. What I feel as being a grippy rear may be the result of too little front grip, like I mentioned at the start of my post.

I'm just not sure about how to get to work on this car.. that may be my biggest gripe after all. It behaves kind of weird.

can't find a starting point eh?
well, I'm sure DTC's settings work well, but I haven't tried them.

Here's another starting point for you:

ok, like I said I was going to do, I've dropped the bound and rebound and spring rates, and increased ride height to try and get this thing to step out easier and remove its 'hoppy' nature.

I've done a few other things to the car:
I've given it N2 tires, Racing Suspension, and a Stage 3 weight reduction.

Here's my current setup (nowhere near complete yet):

Suspension:

• Spring Rates: 11.7 kgf/mm | 10.2 kgf/mm
• Ride Height: 80mm | 80mm
• Shock Bound: 3 | 5
• Shock Rebound: 4 | 5
• Camber Angle: 2.0 | 1.0
• Toe Angle: 0 | 0
• Stabilizers: 5 | 5

Aids:

• ASM Oversteer: 0
• ASM Understeer: 0
• TCS: 0

I'm still testing at Deep Forest with the DS2, btw. These settings may feel awkward at a different track, I don't know.​

My very first step was to set the bound to 6 | 6 and rebound to 7 | 7. This didn't cure the hops, but cars generally behave pretty good with such a setup.
I also raised my ride height to 80 to generate a little more lateral weight transfer with the higher COG.

I arrived at these spring rates with a little math - it's no exact science, but neither is drifting. Here's my process.
I dropped the weight of the car from 1250kg to 1062kg. This lets me soften the springs without risking bottoming out. I estimated I could arrive a safe value by multiplying my current spring rate by the cars new weight as a percentage of it's old weight.

(new spring rate) = (old spring rate) x (new weight / old weight)​

That got me from 16.2 | 14.4 to 13.8 | 12.2


I also have raised the ride height from 65mm to 80mm. So by the same math and logic...

(new spring rate) = (old spring rate) x (new ride height / old ride height)​

So now I'm at 11.2 | 9.9

Those rates worked, but for my tastes the car felt a little too mushy and slid a bit too much. With another 10 mins of trial and error I found a comfortable balance at 11.7 | 10.2.


Then I wanted to remove the hops. There's few things in GT4 I hate more than a car that is bouncing around while I'm in the middle of a drift. The bound and rebound I posted there was all obtained with trial and error and observation. I'll admit that they look mushy, but I haven't experienced the typical delayed reaction to steering input with this car that others cars might do with such soft dampers. It still works for me.

It hasn't fully cured the hops at Deep Forest (it's still a bit bouncy on the main straight), but I think it is definitely better than stock. I tried the car at TM and it didn't bounce around at all for me, so I'm happy leaving it as is.

If you plan to use this bound and rebound as a starting point, be careful if you choose to modify it. Dropping the front rebound any lower (at Deep Forest) gave me a lot of understeer. Dropping the rear bound increases understeer as well, but not as much.


Ok, so after the changes to those 4 suspension... things, the car has become much more driftable. Feinting works quite well - so much so that linking turns 2, 3, 4, and 5, and connecting to turn 6 at Deep Forest feels almost trivial. As well, 390hp makes power-over more than possible. There's still some understeer at turn in if you don't utilize and lateral weight transfer before the turn... so no lift off or braking yet. I don't know if I'll even try to correct that with the spring rates. I still have camber, and stabilizers to play with (and maybe toe...) to fix that up. There's also LSD settings and brake balance to fiddle with later.

If you're having a hard time getting started, maybe give those a shot. They're not complete settings yet, just my progress after 1 hour of tinkeringr this morning.



I guess while I've sort of brought it up, does anyone else find the brakes to be highly innadequate on this car?
maybe I'm just not used to a 390hp drifter... but I find it to be a real chore trying to get this thing slowed down going into turn 1 at deep forest, and the left hand sweeper coming off the back straight.

[edit: sorry, this post got lengthier than I tought it would ]

 

[Ske]

I don't have any problems with the brakes, more so with the engine....

My settings so far:
Parts:
- N2 tires
- Stage 2 turbo (!)
- Racing gearbox - auto 10
- Custom LSD - 10/47/10
- Brake controller - 3/18
- Racing suspension
-- Springs - 10/8.5
-- Ride - 80/90
-- Bound - 6/5
-- Rebound - 5/4
-- Camber - 3.0/1.2
-- Toe - 0/0
-- Stabilizer - 3/2

Well it wasn't the obvious choice as this car already has a lot of HP.. but the turbo gave it some sorely needed torque to play with. I still wish for more responsive steering, but it's definitely getting somewhere. The added torque makes it easier to increase the angle without slowing down... The steering feels too numb to accomplish that at higher speeds.. downforce would probably have helped. It also helps keep the wheels spinning when you drop the revs.. downshifting will often cause this car grip in my hands.

It's anything but forgiving though... the entry needs to be spot on. The characteristics of the engine also makes you have to work a little extra to keep it between 6-7k rpm. I want to get the rear to come around even easier, especially on braking and lift.. so It's not over yet.

 

[ekmatt9]

Would it be cheating, if we put rear toe up? I've noticed it helps cars drift...

 

[Boundary Layer]

heh, that's what I like about this car - you can't attach a wing. Getting it setup is more challenging.
It would have helped though.

I've graduated from Deep Forest and was working on my setup at Apricot Hill before the Leafs and Habs game came on (can't miss that, I'm only here b/c it's the second intermission right now ). I noticed a few shortcomings in my suspension setup. Coming from Deep Forest the car was setup more for quick direction changes as opposed to sweeping turns. The spring rate felt a little too hard for this course. I haven't got it quite right yet, but I'm thinking a front rate between 10 and 11kgf/mm and a rear rate between 9.5 and 10.5kgf/mm would be more appropriate for my technique on this course, as opposed to the 11.7 | 10.2 I posted earlier.

Ske, I'm now having the same trouble on my setup with the steering. At Apricot Hill if I get into a highspeed drift on turn 1 & 2, turn 7, or the final turn above a certain angle the front wheels become useless. I can't be sure, but it looks like its something like 30-35 degrees at a speed greater than 100km/h (may actually be closer to 130km/h). Below that I can still control the line with the steering. But above that the steering changes have little impact, it all comes down to throttle control mixed with rapid brake or ebrake taps.


Other than that, I'm happy with my progress on the car so far. On low to medium speed drifts it is quite controllable and its pretty easy to stetch a drift out to link a few corners together. I've attached a fully customizeable LSD and set it to 10 | 20 | 10 for now. That's removed some of the understeer from the car at corner entry. But you still cannot initiate by lift off. I've fiddled with the camber and brake balance, but nothing worth sharing yet.

edit:

Would it be cheating, if we put rear toe up? I've noticed it helps cars drift...

Cheating? I certainly wouldn't think so. Give it a shot.
I'll give it a try on my setup after Toronto beats Montreal (tied 2-2 right now ). Usually I shy away from changing toe settings because it can seriously destabilize the car, but this car behaves so oddly... who knows what it will do.

Nismo Fairlady Z Z-Tune (Z33) '03



Alright, this car sucked to begin with When I first started off with my usual settings, it was insane!!! It was so horrible. Nismo couldn't and GT4 couldn't have gotten any worse in tuning this car for grip and drift. Sorry guys So then I tried different stuff on it. I tuned the LSD, and I thought it was fine...But it wasn't. Instead of pressing okay...I pressed back. So I didn't know that. I went to go tune my LSD again, I saw it was stock. I was furious!! Then I tried different LSD Settings over and over and over again. And I found one's that gave the necessary "push" in the car. And I was searching online for fun...And saw that this D1GP group, took the stock 350z motor out, and put a SR20DET Motor because the 350z engine is all front heavy. And the swap they did worked. We can't do that in GT4...So I tried ballast weight and still nothing. So to make a long story short...I tried to make the car simple and smooth, and nothing worked...And these settings are okay...They're kind of choppy.

Parts to buy:
(some of these things may already be on the car)
Racing Exhaust, Stage 2 Turbo, Racing Brakes, Brake Balance Controller, Racing Suspension, Full Customize Transmission, Full Customize LSD, Stage 2 Weight Reduction, N2 Tires.

Settings:

Suspension:

DRIVING AIDS AT 0!!!



Yeahh, I changed the rims, got a problem
The black one's were too dark for my pics...And I wasn't going to edit them...Oh, btw, the smoke isn't photoshopped, these are all regular replay mode.

If you have any trouble with the car, please PM me, or reply to here about it with my quote or something 👍

 

[Ske]

Updated settings now.. these turned out to be a lot looser, but quite interesting.. especially since the front wheels seem more connected in higher speed turns now. It's still immune to lift/brake entry attempts but feinting combined with brake or power works a charm.. needs heavier feint at high speeds.

It's now easier to catch the long brake entries which I've come to like.

Springs - 9/8
Ride - 90/90
Bound - 6/5
Rebound - 6/3
Camber - 3/2
Stabilizer - 3/3
LSD - Stock (!)
Brakes - 3/18
Stage 2 turbo
Stage 3 weight loss programme
N2 tires (N3 might be an option too)

 

[ekmatt9]

Ske, put your rear camber down to 1 or 1.5...I tried your settings like that...the rear grips a little IMO

I just increased it to 2 to make it slippier at entry and grippier while drifting

 

[ekmatt9]

Ohh, alright. Gotcha

 

[Boundary Layer]

Bound - 6/5
Rebound - 6/3

that's interesting....
I'll give stiffer front bound and rebound a try on mine. I have a hunch that this is where the lack of steering response comes from. The front needs something to plant it a bit more... I just hope the hops don't get worse.

I'll post thoughts about that, and the toe suggestion in a bit.

 

[Funkshen]

Wow you guy's have gotten to this way before me.

Im gonna go for a run now, And i think ill use DT_C's settigns as a start off.

 

[Ske]

Ok, this car has now officially been pimped.. or something like that. By softening the springs and stabilizers further, I'm now quite happy with the Z on MF, AH, AR, GV and TM.. which would mean I'm generally pretty happy with it...

Spring rates down to 8.0/6.5
Ride still 90
Bound still 6/5
Rebound still 6/3
Camber still 3/2
Stabilizers down to 2/1
Brake balance still 3/18
LSD still stock
Turbo still on

The Z now drifts like a dream... the bouncing on TM is as good as gone, it's more forgiving, the steering has come alive, and the power is put down nicely

hehe, ya.
Really enjoying this one. Much more challenging than Volume 1's FD


Ske - those damper settings work quite well. Very neutral turn in.

Right now I have bound 3 | 6 and rebound 5 | 5 with springs at 10.6 and 10.0 (i still feel like I should go .5 to 1.0 kgf/mm softer) and camber at 2.6 | 1.4

These damper settings seem to have more oversteer at turn in with the throttle off. Hopefully this gets me one step closer to using lift off, but I think the LSD needs a retuning.

Haven't played with the toe yet.

 

[Funkshen]

Comments: My God ive actually never drifted anything quite like it, it is a purely awesome experience to drive it, infact i love it to bits!. Sure Feint might be your only way to initiate oversteer, but once this puppy is sideways she guns it, fighting for traction mid-drift is not an issue.. and exits are fine, the car sticks to the line. it's all positives basically for me.
Downsides: Lift-off and Brake drifting techniques arent really able to be used in this car. It struggles to loose traction. but with a slight bit of sway, and precise steering inputs. she stays sideways for aslong as you like.

O.K., So I Started off with DT_C's settings, which proved a great starting point.

But i have a really aquired taste for drifting, rather i enjoy much more oversteer then theres really intended, so i have heaps of room to muck around instead of not having enough oversteer and really fighting for the rear end to break loose entry, mid-drift and exit. (This differs from DT_C's style)

(PLEASE KEEP MY TASTE, FOR A LOOSE REAR END IN MIND)

So heres how ive gone.
My settings are really relying on Boundary_Layer's and Ske's findings so far, in which i can't really argue, so infact i have to agree. But like i said my aquired taste has had to break a few law's.

Settings: (So Far) '03 Nismo Fairlady Z Z-Tune (Z33) - 493HP
(Tested on Trial Mountain)

Modifications:

-N2 Tyres
-Stage 2 Turbo
-Fully Customizable Suspension
-Fully Customizable Transmission
-Racing Exhaust
-Racing Brakes
-Stage 2 Weight Reduction
(i'll buy LSD when im gonna fiddle with it, for now its standard)

Suspension:
-So first step was a bit of trial and error with my spring rate, where i was really pushing for a stiff rear end, After 10 Minutes [11.6 | 10.8] Proved to work for me.

-Next Step Ride Height, not a big thing in my settings, but since i dropped a few kilo's with weight reduction, i had to compensate.
[75 | 75] Worked alright.

-Next Step Bounce, Rebound. This is usually a make or Break Situation, but this time round everyone seems to have it different, Personally Settings work fine with Bounce [ 5 | 5] and Rebound [ 7 | 5]

-Next Step Camber. As this car really struggles with understeer, rear camber was a must in my situation. [ 2.6 | 1.8]

-I'll Leave Toe alone, [ 0 | 0]

-Next Stabilizers, I Just boosted front and rear up a notch, [ 5 | 5]

Transmission:
-Since im testing On Trial Mountain I like to take Turn 4 (Tunnel) in Third Gear. so Auto Set was put too [ 10 ]

AIDS:

Aids Ofcoarse at 0, but it's tempting to add a few to ASM Understeer isn't it?
-ASM Oversteer [ 0 ]
-ASM Understeer [ 0 ]
-TCS [ 0 ]

I'm yet. to fiddle with Brakes and LSD.

A Great Car!, I love it!

 

[Boundary Layer]

maybe someone else will post their thoughts on this... I don't know fi I'm just imagining things or if it's true.

I'm still fiddling with my spring rates... I was testing them at 10.0 | 9.6 and on long sweepers the front would still want to wash out on me and it felt somewhat disconnected (as everyone seems to have said).

So for the heck of it I went to 9.0 | 9.5. I know there are people out there that always use a stiffer rear, and that's fine, it's just not something I normally do. But I wasnt entirely happy with the front stiffer to this point so I gave it a shot.
There wasn't and drastic change in the car's entire demeanor, but it fixed up some small things that had been irratating me:

The car felt slightly more agile at high speed. I could feint from 200km/h where previously it would only want to travel straight at this speed - feinting wasnt much of an option above 180km/h for me.
On sweeping turns the front felt somewhat less prone to washing out.
The entire car felt much more connected in mid-drift. I felt like I was more in control, and less just 'along for the ride'.

Additionally, low speed maneuverability and turn in hasn't suffered.​

Maybe someone can call me a crack-pot or something if this just doesnt add up or feel the same for them. I might be to the point with this car where I'll believe what I want to believe.

it does still take a fairly decent feint to initiate drift unless you get some help from an elevation change.

 

[Ske]

Update:
I'm keeping my suspension settings so far (after fiddling with it for a while), as I like the settling lazy feel and slight body roll. I'm also going for a 10/45/10 LSD, no turbo and N1 tires (in combination, one doesn't seem to work without the other)... I've tried ballast, but it didn't seem to make the car very happy.

Feinting with a little help from the gas pedal.. or plain power over seem to be the only ways to keep this car going for me... All in all, I think the car is turning into a decent drifter, but the powerband and torque give me a giant headache... long sweepers are still pretty awkward because you have to hold back and not accelerate (or you'll quickly redline and be in deep doo-doo).

At least the suspension seems to behave...

Test tracks used so far:
Apricot Hill *****
(Seems pretty good here)

Midfield Raceway ****
(Powerband issues at the double sweeper and the uphill S)

Autumn Ring ***
(Angle control could be better.. also some powerband issues)

Grand Valley (full) ****
(Fairly good, though it's hard to link the double apexes between the tunnel, it just won't settle correctly when going from left to right.. More torque would definitely have helped right there...)

Trial Mountain ***
(I keep entering too fast, and the car has a tendency to lose angle mid drift)

Deep Forest ****
(Needs some convincing on turns 3, 5 and the final left, but feels quite decent otherwise. Definitely torque issues when trying to link from turn 6 through the dip)

 

[Boundary Layer]

Ok, I'm retiring the car for today. I have some serious studying to do for Stress Analysis and Fluid Dynamics... GT4 isn't helping me accomplish much. I'll pick it back up on Tuesday - I'm not done yet.

Edit: The following settings suck. Better ones are on the way.

BL's Sunday Settings:

The car has gone through a few evolutions this morning. I'm becoming more and more comfortable in it, but it still lacks the ability to do any serious braking or lift off drifts.

Parts to buy:

Racing Brakes, Brake Controller
Full Customize Transmission, Full Customize LSD
Racing Suspension
N2 Tires Front and Rear
Stage 1, 2, & 3 Weight Reduction
Oil change and maybe some nice rims
~390HP (stock)
​

Settings:

Suspension:

• Spring Rates: 9.4 kgf/mm | 10.6 kgf/mm
• Ride Height: 80mm | 80mm
• Shock Bound: 3 | 6
• Shock Rebound: 5 | 5
• Camber Angle: 2.6 | 1.7
• Toe Angle: 0 | 0
• Stabilizers: 5 | 5

Aids:

• ASM Oversteer: 0
• ASM Understeer: 0
• TCS: 0

LSD:

• Initial Torque: 10
• Limited Slip Acceleration: 50
• Limited Slip Deceleration: 10

I haven't given too much consieration to my brake balance yet. I'm currently using Ske's balance of 3 | 18. I still plan to fiddle with the LSD settings a bit more.

The car is responsive and the steering feels quite direct. I was checking the balance of the car by doing a few grip laps at AH, and it does understeer if you misjudge your speed entering a turn. But off-throttle turn-in at a reasonable speed is close to neutral, oversteer develops just after turn-in if you're on the throttle.
I'm still dissapointed by the fact that feint and dynamic entry seem to be the only options for successfully entering a drift with this setup. Also, highspeed maneuverability (over 200km/h) is still lacking.

 

[G-T-4-Fan]

Oh glad you guys are going anywhere. I've tried it now for a few times too, but without succes. It'll never be a good drifter for me. If I drift, I feint pretty early, getting into some light oversteer, and maintaining that untill I really come to the corner where I smash the brakes to increase my angle from almost none to very much.

I cant do that in this car. And I'm thinking....since this car feels really drift-unbalanced, to roughly try and balance it with N3's on front and N2 in the back. Or N2's in front and N1's in the back.
I never did that with any car EVER! Not even in my beginning but I guess this will be my first time...

If that doesn't work, then I'm switching to your settings.

This is interesting, Because believe it or not most of my drift cars have a stiffer rear end, because i enjoy a loose rear. But this car for some reason, i don't feel had the same compatability.. The car initiated the same way, but the ride in general felt unstable, and rather unpredictable, and gave more understeer.

Example, i started off with [ 10.4 | 11.3 ], it felt alright.. the way i like it.
But [ 11.6 | 10.8 ] felt much more reliable, and to the point where i could push the car a little.

So it's really mixed emotions on spring rate. I find it very interesting to see different views.

 

[Ske]

Well, I have documented (at least for myself) that a SOFT rear can provide loads of power off oversteer in cars like the Speedster, Clio, Audi TT, Mazda FD RX7, various race cars etc.. whereas a stiffer rear would cause them to go neutral or understeer. In fact, I haven't yet seen a stiffer rear give MORE oversteer than a softer one... I don't feel it's the case for this car either, this Z seems to be just.. um... defiant or something.

Extensive testing going on as we speak.. still trying to unravel the mysteries of gt4 damper tuning

 

[ekmatt9]

Has any one tried my settings yet? Any thing wrong with them? Let me know!! I tried some settings again, but I think the other one's are better...I might post them up soon.

Well, I have documented (at least for myself) that a SOFT rear can provide loads of power off oversteer in cars like the Speedster, Clio, Audi TT, Mazda FD RX7, various race cars etc.. whereas a stiffer rear would cause them to go neutral or understeer. In fact, I haven't yet seen a stiffer rear give MORE oversteer than a softer one... I don't feel it's the case for this car either, this Z seems to be just.. um... defiant or something.

Extensive testing going on as we speak.. still trying to unravel the mysteries of gt4 damper tuning

ya, I'm on record quite a few times saying that a soft rear = more oversteer.

mystery indeed.
Ske and I unraveled one or two questions (well, Ske did more of the unraveling than I did - I just played dumb and came up with more questions than answers). But there's still a lot of odd things happening with this Z.

We certainly proved with the use of one poor S2000 that stiffer rear springs should produce more understeer at corner entry. So I'm very puzzled as to why I prefer this Z with a stiff rear. It just doesn't follow my normal trend.

Studying is taking a backseat again. This Z keeps calling out at me.
Going to take what Ske and I think we figured out about dampers and apply it to the Z, and then see how much worse I can make it.

this looked like fun and my kai is not working quite yet so here it is....Dkings settings for the z....
I noticed off the bat that this car is a natural understeerer and to fix this i set the rear stabalizer stiffer then the front....now the ass comes out like other cars...still testing but here are the first group of settings....
Parts:
N2 tires
Full Drivetrain
Race suspension: 14.6/12.4 spring rate
55 mm both F/r
bound and rebound set at 6
camber = 3.0/1.0
stabalizers= 5/7
Full custum lsd
Stock power.....
brakes at 3 both
.............................
This is the first group of settings for this car tested on trial
