Those that can drive, drive... those that can't drive, tune... or in your case, talk bollocks about tuning.

At least I'm fast enough to have been to the GTA finals... all you can do is talk (or in this case, type 39 pages of drivel) lol

Big Fucking Deal, nobody gives a shit how close you came to GTA, you didn't make it. Im just playing a video game and enjoying as I see fit. I drive all the time in GT6, got 600+ driving hours, I have tuned cars posted set ups and talk a lot about the tuning and physics in the game having figured out more than most about what goes on behind the scenes. I don't run around bragging about how much faster I am than others (Im not slow Winky Winky ) I was given a big dick by God and don't have micro penis issues like you. Oh and its something ladies can see in the way we are, they sense it and they are attracted to it, that's why we don't end up in the "Friends" category we end up in the "fuck friends" category Winky Winky but you wouldn't know anything about that.

All I do is enjoy GT as I see fit, I don't have to post a tune, or post a time I do as I do despite the likes of you, you're a nobody around here and nobody here gives a shit about how close you came to GTA, you didn't make it and this ain't GTP. Around here if you want to earn respect you HELP people instead of acting like your better than everybody, that Bullshit don't fly around here.

You seem very fixated on the size of my dick... would you like a photo?

I didn't come here for respect. I came here to laugh at you.

Its already circulating online , looks like a lil mushroom top in a fur patch lol You were Mr Chow's body double in the Hangover movies lol. I bet you think size don't matter lol you have to believe that don't you. The guys with micro penis issues are easy to spot, like those with a Napoleon Complex pretty much the same thing lol.... I figure if your real short with a big dick, you don't feel so bad about being short lol...

I know why you came here, Im glad so I can have fun with you, at GTP I just get banned, get's old as they delete post n shit. This is not GTP, its me laughing at you...

Hey man... I just created an account here after hearing about this thread from GTP. I'm a nobody over there, I'm sure you've no idea who I am (I'm one of the people submitting data for that Camber Experiment). While I certainly agree with a lot of what you've said regarding camber, my god, you are one angry dude! LOL I will admit, you did have me laughing with some of your responses.

I'm of the opinion that camber doesn't work "correctly", as in, the way it would be applied in real life...but, I do believe that applying camber to certain tunes is beneficial in many cases. It certainly is with MY cars. And frankly, I don't care how anyone else's car drives. I only care about my own. As I'm sure most of us do.

I'm no alien. Heck, I'm not even a "fast" driver as you can see from my submitted data in that Great Camber Experiment on GTP. I get a lot of enjoyment out of playing the game the way I like to play it. I try to keep things as realistic as possible. Sadly, I see way too many people turning all of their cars into practically the same thing, tossing aside the car's individual character and traits that made it special in the first place. I don't bemoan the fact that many driver glitch tune if they're going after the fastest possible lap times - heck, you have to do it if you want to squeeze every last drop of speed out of a car. And even the way I personally apply camber is sort of glitch tuning because I have to apply values that certainly don't match anything I would see in the real world.

I know you've had a hell of a lot more history on GTP than I have. I've only been posting on their about a year. Personally, I've always found Stotty to be a honorable, respectable poster, but I'm not here trying to change your mind. You don't strike me as the type of fellow who's mind would be changed by a stranger's comments anyway. There absolutely is, however, problems with some perceived social hierarchy at GTP - supposed regular users who seem to walk on water protected from up on high - and that does bother me quite a bit.

I've joined this site so I could respond here and I've bookmarked this thread. I'll be popping in from time to time to see what thoughts you're sharing over the next week or so... BTW, I just tried your Subaru BRZ tune and I really enjoyed it. The BRZ/FRS/86GT is one of my favorite cars in GT6 and I own several with different tunes. I think I'll be using yours quite often now.

Thank you...

Did they tell you I was Jack Napier?

I know who you are, I also appreciate very much the effort you and everybody who has submitted data in the camber Experiment. The BRZ you like was originally tuned to be the test car in the Camber Experiment choosing the BRZ as its the next Miata IMO. Awesome Entry Level Racing car. I had been planning the Camber Test behind the scenes around 1.07 but banned for BS at this point I pretty much stopped creating new accts at GTP and Dolhaus ended up putting on a good test, not exactly as I would of (I think offsetting the values is a must and keeping them equal is not as good as individually tuning them) but its the first step in the right direction I believe. CargoRat actually did the most interesting blind test that elements of his test should find their way into the camber experiment, but that project is going good and can evolve to include some of CargoRats methods in a future edition.

It may appear so, but Each time I got banned at GTP, I came here to vent, and periodically when members at GTP are talking my name but on GTP where I cant defend myself, SO I post here to vent, as GTP members dont get special treatment. So while all the HATE to me is spread across many many threads and in general talk every now and then, I all of my responses are in this one thread. Im venting and making jokes. Id rather let it out then bottle it up.

This is a interesting line, while you are correct, you are also wrong. It works as it should but there is a key difference in the GT6 suspension and real world suspension and these differences are key here. These differences change us from tuning camber to a cars individual suspension geometry and instead we tune to the GT6 suspension geometry.

The suspension Geometry and how ride height adjustments are made is critical here. Taking the differences into consideration (actually doing it instead of just saying it) Then camber works as it should in practice.

For example car in real life have different amounts of camber gain and caster angle, and this impacts our static camber angles, but in GT6 there is generally the same amount of camber gain on every car, but different caster angles. The camber gain and suspension travel in real life changes as we adjust ride height and much of real world camber tuning is to accommodate dropped ride height altering the stationary position in the camber gain arch. In GT6 camber gain is pretty much the same on 99% of cars and while caster angles are different there are only a few angles they use in GT6 vs a much larger range IRL

Put the differences in the suspension aside and camber works as it should, relatively. Sure its possible the scale is not perfect, but it really doesn't matter. The FACT of the matter is Camber is not broken, there are just a lot of people who don't really know how the GT6 (Not real life) suspension works in the GT6 world and if they don't know this there is no way they can effectively translate real world tuning techniques and principles into GT6 as you have to accommodate the GT6 suspension in order to do so effectively.. This is why so much of my time was spent figuring out how the GT6 suspension works and why I value the SpecDB data that confirmed my theories. Sure it felt great my testing figured out most of what was going on before the SpecDB confirmed it, its more important the SpecDB revealed the data that it did, and the guessing game for me is over.

Thats all you need to know really, how you can use it for yourself, an look at it like this, its just another tool in your tuning arsenal, where overlooking it would be one less tool in your tuning arsenal.

As long as you enjoy the game your way, its all good. Some folks dont even drive really, they take pics only, all the power to them, There are some pics at GTP that are epic and show some skillz as a photographer, there way of playing is no better than mine.

I personally dont give a rats ass about leaderboard rankings, Ive set records in GT games that far surpass a learderboard time. I set pretty much every land speed record in GT4 (The last GREAT GT) and 10 years later they still hld up. While yeah Im a bit stoked they are still standing and it was the shit to me back on 06 Ive grown out of that and today I enjoy GT much differently, I even enjoy GT6 much different now than when it first came out.

I have much more appreciation for stock set up on cars (GT6 exclusive cars have taken it up a notch) Im not so anal about no ABS on modern cars that have ABS but still got no respect for those running it on every car those that came with it or not. Im more about enjoying the drive than pulling out my hair chasing times. Usually after enough hair got pulled out I top whatever time Im after and beat whoever challenged me, but the payoff was never worth the frustration nobody gives a shit, not even me really. Especially to find the competition uses assist IMO cheating, not interested in it at all.

I like to enjoy the game driving cars I like, where I like, and sharing replays. I dont even need to put the time in many as its just not all too important in the end, Im just having fun.

This is a shame, as it IMO kills what makes GT so great of a game and instead makes GT feel like Ridge Racer or F-Zero, and its funny how those games are used to poke fun at like GT is at a higher level when they use glitch tuning to bring GT down to that glitched up BS

I don't even mind, if they are after leaderboards and whatnot, sure go for it, but dont shit on the guys who dont care about leaderboards just trying to get as real of an experience as we can, just because they can glitch tune a fast car taking advantage of assist and exploits doesn't mean real tuning doesn't work, if when you turn off the assist those cars fall on their face as most WRS winner tunes do when the assist are turned off to me they are shit...

For example Driving line and Gear indicator make people feel like incredible drivers, but they cant drive without them and in the real world they do not exist.

I think it really doesn't matter, all things taken into consideration if you figured out a way to use it in your tunes to make your cars feel and drive better for you thats all that matters. You would be surprised relatively all things considered they are not as different as you might think.

10 year ago I was banned for refusing to give up my cars set up being accused of cheating being too fast and the only way I could prove Im legit would be to give up my settings. I refused and while the debate might have been a bit jaded on both sides as NOBODY was liking me coming in and setting records SOOOOO much faster than everybody so when I refused to give up my set up without warning I was banned..... Nt even a banable offence, just Banned for NO real reason aside from being too damn fast. Im sure you have hear of folks getting kicked from a lobby for being too fast, I got banned from GTP in GT4 days for being too damn fast...

I see him as half and half, while I see many great post from him, hes also a lead dickhead and everything I posted on him I stand By, well aside from the obvious jokes just fucking with him. He came here just to give me the finger he didn't even have the balls to address the comments I made that referenced him. So I shit on him. lol

GTP's biggest issue is right here, Diplomacy, Tact, Fairness escape MANY (not all) of the moderators and they have a clique of regular members that seem like they re under mod protection, some of them are just pure fucking tools.

Glad you liked the BRZ, you should check out the Lambo.

Your welcome to pop in any time, I only will smash talk the guys who come over from GTP to give me the finger. If come over respectfully, you will get treated with respect.

Oh, I look forward to trying your Lambo tune. I have lusted after Lamborghini's since the day I saw my first Countach around 1980. In fact, THAT is pretty much THE reason I bought GT6 in the first place. There are so many cars that I would love to drive in real life, but I probably never will, so I get to escape into this fantasy world and drive an Aventador, or a Nissan GT-R Nismo whenever the hell I feel like it. I can drive as fast as I want and even if I crash, I don't get hurt. Thankfully, these games have gotten considerably more realistic than they were 20 years ago - which is pretty much how long ago I stopped playing games.

Forgive me for not addressing all of your points from your response to me. The 'T' and 'N' keys on my keyboard are fucked and pressing them 5-15 times to make a letter appear is not fun, so I am trying to keep things short...which is hard because I tend to get quite verbose at times. LOL!

Nobody mentioned "Jack Napier" to me. I think I found this thread from the general discussion thread about camber - the one where CargoRatt did that blind test, which I agree is the best way to do it. I think DolHaus is doing a great job with our Camber Experiment, but I hope as we advance through this experiment we can just drop using values of 6, 7, 8, 9 & 10. I don't think there will ever be a situation where that amount of camber will be helpful - not the way it works in GT6. And while I will confess I'm a terrible GT6 tuner, I can tell what each tuning value should or shouldn't do to the car. I totally get what you are saying about the suspension programming/setup in GT6.

It surprises me that a company with as much history and financial backing as PD has could make automobile settings so convoluted. I don't have the first clue as to how iRacing or Assetto Corsa or pCars, etc are to A) drive or B) tune. But, I can't imagine that in order to be "fast" you need to drop the rear end as low as it will go and jack the front end as high as you can, for one example. I have no experience with the other versions of Gran Turismo, so I don't know if it's always been like this when it comes to tuning, but WHY can't they just get it freakin' right?! Could you imagine playing a baseball game where you select Curveball when you really want to throw a fastball, a fastball when you really want to throw a slider? Hell no. That would never, ever fly. At the same time, I'm NOT one of those people who shits all over GT6 and/or PD. After all, this is literally the only video game I play. It has kept my interest maxed out for over a year - my friends are shocked I'm still playing ANY game after a month, let alone a year.

That's absolutely terrible that you were banned from GTP just because you didn't want to reveal your setup. Unfortunately, I'm not even that shocked based on some of the things I've seen in my short time there. I agree with you about the cliques that exist on GTP. Cliques tend to happen on huge forums like GTP, but the fact that some of these cliques are basically given special status by certain Moderators is wrong on so many levels. I know a perso who was perma-banned by a Mod who was such a hypocrite it was sickening. I saw the PMs after the fact. It was awful.

I gotta stop typing. You have no idea how fucking pissed I am with this fucked keyboard. It takes forever to hammer out a single sentence. I'm off to try your Lambo tune!

The Lambo is fresh & it was one of my first loves after watching Canon Ball Run as a kid in the early 80's. But in Detroit I learned to work on cars with my Uncle on a Fairlane tubbed out that was basically a drag car he raced on the street. This was back in the late 80's early 90's so I couldn't help get into American muscle and it was GT1 that introduced me to the GT-R and my interest in exports begun, while I still maintain my love for American Muscle & interest/curiosity in exotics.

Its funny how they like the handle Jack Napier, its the Jokers real name in the Batman with Jack Nickleson as Joker. But whatever, Im the Devil over there lol...

IRacing has its glitches too, like tire temp is generic, they have 3 way temps, but the center is always X amount hotter than the outsides no matter what tire pressure or tune you use, tire temps in iRacing are to be ignored.. Just one example, every game has its glitches, even PC SiMS... GT is a console Game and while its Sim based its still a game. Glitches will be found, and many of Gran Turismos glitches are old and a product of the physics engine, the game has basically evolved beyond the techs abilities and GT6 is made for PS3, sorta getting the best of all their work on the PS3 while they take GT7 to the next level on most likely an evolved engine that is not compromised by the techs abilities.

In GT4 days there was still glitches like ride height, just they were not taken seriously as a circuit tune. Fast or not, if the nose is in the sky like a snob bitch to take advantage of a ride height glitch, I have zero respect for the tune in GT4 days nobody did, we used wheelie glitches to exploit speed and shit, but they were wheelie tunes and reversed rake on a circuit tune is a joke.. I dont care if people use it, love it and think they are fast in Ridge Racer Tunes it will never get my respect and the tuner in my opinion is a glitch tuner, same deal. I wont hate on them, unless they hate on me trying to keep it real caring more about retaining the cars character than making them all drive the same. To me its more important each car has individual character than be fast yet drive and feel like all the rest tuned the same way.

It kinda boosted my ego a bit, however its gotten a bit annoying, but its not worth getting too upset over. When your tuning top speeds 50mph or so faster than EVERYBODY else red flags will get raised, but because I got banned at GTP I ended up posting the settings at a different web site anyways and the settings in the end prove I wasnt cheating, its bullshit I was the only one Ive ever heard of in GTP history that was practically forced to give up a competition set up.

Could you imagine a WRS driver being forced to post his set up during the competition? NEVER GOING TO HAPPEN it would be unspeakable... If he was asked and he refused I doubt they would get banned for not giving it up. He also has every right to slam a request as bullshit as that. They only tried for force me to give up my settings after changing the rules for Land Speed Records because of me about 6 or 7 times, giving new requirements to qualify my speeds and they were upset I would meet each new regulation until I was put on the spot to post my tune..... They still haven't gotten over it since GT4...

Its funny. Mods clean up after banning people to make sure they don't look bad, but they didn't clean up the thread well enough and anybody with half a brain can see I got a raw deal and they banned me because they were ButtHurt, I was just too fast for there to be any competition, so like in an online lobby, Kick the guy who's just too damn fast. Its still in the GT4 section...


The Lambo is a fun drive, wish we could paint the rims gold tho lol

Here is a post of Griffith500 replying to JohnnyPenso saying chassis codes have grip multipliers. I figurred its a good point to discuss. I can see the SpecDB data thanks to a friend, however my interpretation of the data is still in its infancy. While I have learned and confirmed much, with so much data it takes time to properly test and interpret the data in code for much of the stuff not as apparent.

Originally posted by Griffith500
You were told in no uncertain terms that the multipliers were applied to tyres. "Chassis grip" was always 1 in GT5.

The consensus from those who did the digging is that the multipliers are for per compound parity across cars.


Whats interesting is the grip multipliers are indeed applied to the tires, but the multipliers are in the chassis code specs. Also i do not believe they are there for "Parity Across Cars" but for tweaking the individual car to the GT6 World.

If it were simply for parity across all cars then equal specs would already do this. When we take a look at a 65 Mustang GT350 and compare it to the Boss 302 then we can clearly see the modern car has more grip with the same tire grade, this is not parity, its the opposite. This tire modifier in the chassis code I believe sets lower grip on the 65 Stang in relation to the modern Stang getting a higher level of grip in comparison on the same in game tires. Its somewhat like the 65 Stang gets 1965 quality tires, vs the Boss 302 getting modern tires for its class, I believe its this same coding that in this way gives modern super cars modern super car tires grip in comparison to older classic super cars seeming to have grip levels of the tires of their day..

It appears more like a overall tread modifier to manipulate the grip to the car. A classic Stang in the 60's din't have as grippy tires available as modern era tires. Racing Hard tires on the 65 Stang are not as Grippy as the tires on the modern stang even when the tires are hacked to be the same size (yes width too)

The Tire Codes in the Chassis code are "treadF" & "treadR" there are also the position codes and tire dynamics specific to the car and tires it came with. I believe the "treadF" & "treadR" are what play the significant role altering grip of the tires, while the other codes do play a secondary role (much less variation from car to car in the codding vs "tread" codes) I believe this will also change the tread pattern appearing on the car like if the value falls inside a given range X pattern is used and if in a different range a different pattern is used. I believe this because they're only a handful of tread pattern variations VISUALLY while there is a much larger degree of variation in the code. The code being a numerical value seemingly higher with the cars that have more grip in their tires and lower on cars with less. It also appears to be higher on the odd ball cars that are magically fast per spec. Its not always equal front to rear, and its sometimes higher in the front vs rear while cars like the YB have a much higher rear than front.

In case some might think its the tire width codes, make no mistake, those are a separate code NGU has been modifying for a while GT6HE has had tire width modifiers since I've first started using it a while back.

"WheelLayout", "wheeloffsetF", "wheeloffsetR" and "wheelbase"

These position the wheels

"GrowInch", "TireWidthRate", "FrontStiffness", "RearStiffness"

These are tire dynamics, different from chassis to chassis and so from car to car, but the variation is small compared to the tread codes.. Both impact tire dynamics however the tread code having a larger variation from car to car leads me to believe its having the larger impact in the variation of tire grip from car to car with the same grade tires. Except for GrowInch that many cars have 0 (I think low profile tires from dealership) while others are inside a 100 to 110 range.

Also while "FrontStiffness", "RearStiffness" are in the same section of the code as the tire data they may very well be about chassis stiffness NOT tire stiffness, its hard for e to say at this point in my testing, and not fully sure if this and a few other details are in my abilities to test without having the ability to manipulate them, maybe in a future update of GT6HE or I can learn how to do it Debugger style, Im not ready to figure out debugger so Ill get a bunch of other shit off my testing list I can test before I see ask some friends to help out with that possibly giving dynamic data or manipulate data for me.
