Duckman, I have a question. I've noticed in your tunings that you've taken a lot of cars and tuned them to very similar lap times on midfield.

After you've fully modified these cars, does it ever feel like you're driving the parts instead of the cars?

Meaning, does full modification strip the personality of the car, and do they start to feel and sound the same?

Ok, so technically that's two questions, but they kind of support each other. I don't mean to bother, but you've done so much excellent work with your tuning you seemed an excellent candidate for the topic.

I thank you in advance for your time.

You post such excellent tunes, I wish I could get you into chassis downforce. Then I could probably stop tuning entirely, I would just soften the springs to around the default of the race suspension and go.

I think Duck agrees that GT4 is highly oriented toward balance, damper rates are relative, rather than absolute and GT mode cars are slightly "de-tuned" from their arcade counterparts.
I am sure he can elaborate, but I think his times are so similar because Midfield is a very simple track in terms of driving abilities, no hidden chicanes or obscure lines, so the times are a clearer distillation of the car's abilities, removing driver skill as a factor. My only issue is that Midfield is almost billard ball smooth, so generally I need a more general tune (I race my friends and likely couldn't convince them to drive exclusively at Midfield- especially when I am always kicking bootie with Duck's tunes )

Like rk said in his post, Midfield is very easy to memorize, and the laptimes you get would be based off the cars performance, not the driver's skill.

Well, to a small degree, yes. For example, my tuned G35 and Speedster sort of handle the same way, and perform nearly identical, too. But I wouldn't say the personality would be stripped (even though the G35 and Speedster have almost no personality IMO. My McLaren will always be an 800hp sluggish boat, my 300C will always be an oversteering monster, and my Zonda will always be an insanely fast car that can't brake.

But, you can say that the personality of this Jaguar has been stripped. I took it for a drive before I didn't mess with the tranny. Now, the extremely smooth shifting that defines this car has been ruined thanks to the clutch and flywheel. It now pauses the speed when shifting (previously it didn't pause; it kept its speed like it had no gears at all), and that ruins the personality of the car.

Like I said, the G35 and Speedster handle almost the same, but I haven't driven them a lot, so I'm not 100% sure. And I also think that the cars don't sound the same. A few sound similar, but not the same.

I read your description of chassis downforce in Canadian Speed's thread, and how to apply it (ie raise the rear ride height 30 clicks more than the front for street cars), and I used that tactic on every tune. Is there something I'm missing?
And BTW, what does chassis downforce do? Does it stabilize the car at high speeds?

Well, sometime soon I need to get the feel of too stiff spring rates and too soft spring rates. The Jaguar drove much more smoothly than my other tuned cars (maybe it's because the Jaguar is an uber luxury car), and the funny thing is that I softened up the springs more than usual, and I have never did that to a car. I am beginning to think that the spring rates on my cars are too stiff.

I completely overlooked the "144" and read 114, mebe I was flustered or sumtin.
I would say that chassis downforce's greatest asset is high speed stability, especially on the smaller sports cars like the Elan or '68 Nissan Fairlady (Datsun 2000). It tends to bias the steering toward oversteer, but the effect is mild and probably in deference to some other factor like weight transfer or something, I usually notice a kind of twitchiness if i've overdone it (I have experemented with 50mm rake). I can't help but feel the ground effect stiction is exagerated in the physics engine because real LMP cars use only slight rake (I think about 2% and they are carefully tuned in small fractions of an inch). I came across my values using the famous (to me) rise in The 'Ring. Every car I tuned there displayed aggrevious suspension bottoming symptoms until I raised my suspension to the middle of the scale, which was almost always default. the amount left over to rake the chassis was a suspiciously round figure, proving (to me) here was yet another "pattern" where the kids at Poly fudged or "manufactured" tune states. The Formula F1= 10mm left over after setting for bottoming. The LMP's= 25mm left over. JGTC type cars= 25 to 30mm left over, etc., etc.
And yes, duck, I'm a slacker, The only reason I learned all this stuff was to beat my friends on the TV, and it just didn't seem like anyone else was doing it. My "heart" sank when I noticed the August date in //M-Spec's guide and here it is, almost August again, think it's ever gonna change? I will gladly and unashamedly plagarize your tunes into my Playstation if I can win with them, because I believe PD didn't make the Physics Engine sophisticated enough to have any but one ideal tune state; if you got it, you're The Man. 👍
I'll still argue over semantics like a dog wrestling for a bone, just for the fun of it.

That's a good thing. Most fully modified cars are understeering pigs.

When you race your friends, do you do it in Arcade mode? Or do you make a laptime and a replay in GT Mode? Because with the former, I've "heared" that set-ups on cars in Arcade Mode aren't in effect. Hopefully, that isn't true.

That's why people like me make tunes. So people like you can use them and wipe the smirk off their friend's faces.

I believe there is a good base set-up for the suspension. I set my suspension to about the same settings for each car, tweak the suspension slightly as needed, then use the LSD to make the car corner well. I don't think I have the ideal tune state, but I do believe that what I'm doing to the cars is working well.

The cars aren't broken, but we want to get the most out of it. For example, a fully modded car that isn't tuned will gain at least 3 seconds in a laptime at Midfield then a car that is tuned. Let's say that you are losing by a second in a three lap race at Midfield. When you apply a proper set-up, you will probably win by 7 seconds (factoring in the occasional mistake and passing the AI). So unless you really want a challenge, it's always better to use a tuned car than an untuned one. After all, you're going to get the same amount of A-spec points anyway.

We do have a "leaderboard" of sorts, I hold the somewhat unchallenged 5'56 & change in the Bim V-12 at Nürburgring. My friends are more into the formula circuit and I cannot touch the low 1'16 at Côte Big larry claims, I have yet to witness it; I am thinking of enabling asm to get those last two seconds...We usually race 2 player which allows selecting from your own (or his) garage, a feature I am sure PD included so you could race your own tune, unfortunately, because of some resource issue, like the jittery screen sometimes experienced during races that have a lot of open cockpits, the steering bias shifts strongly to oversteer and it is extremely embarassing to watch my beautiful tunes fall to pieces on the big screen. The best workaround I have yet discovered is to tune modified cars with race tires; since the computer allows you to select only simulation or sports tires in 2 player, the understeeriness usually assosciated with sport tires on a racing tire tune almost exactly balances the 2 player oversteer. We have yet to link two systems to see if the combined computing power eliminates the problem, but it is a theory.
You can experience this yourself, just go to Arcade, set for 2 player and take a drive on the split screen.

You may be surprised to learn I have seen the A-Spec points offered for a race change in response to a single click adjustment on downforce. Factors that affect A-Spec points are: tires, power (hp), weight and downforce. There may be others as well, I saw a thread in GT4 General that explored this pretty thoroughly.

wait duck, u noe that gt4 automatically puts u in a race wiht similar hp cars (ur 500hp maybe they have 474 or 525) to make up for thier lack of skill, and there is a limit to that. that limit is shown when u win 1 point races, 1 point race means ur gonna pwn thier faces and tha tur hp whoops and so does ur tuning. for example, my races range from 1-9 a spec points, im proud that i can effectively put my tuning strat and (kinda)skill into the car wiht not a huge hp diff from orig and make it a maybe 4 point race and pwn the crap outta them. the points is the overall tune, like when i take my spec-c out to the snow, its a 1 point race, but i cant win for ish.
