Again, in GT5, I could have shown you picture after picture of cars with extremely high front ends cornering faster and going faster in a straight line. It's illogical but it happened. Pics mean nothing when it comes to GT physics.
OK, here comes a blurb from "Team Viejo", the oldest replica racer on GT6. (that would be me)
Long ago and far away, in Mustangworld, I decided to make my 96 SVT Cobra into a race/rally/track car, and barely managed to keep it street legal. After spending around 25,000 USDollars on suspension alone, the car began to handle so well, that Porches and Vipers and other hot cars would be staring in their rearview mirrors at the very close front end of my Mustang, in the corners!!!. (Had a Cobra R hood too!)
Basically, the stock suspension was thrown away and rebuilt from the ground up. Gee, this sounds familiar to us GT guys doesn't it? The front end was converted into true Macpherson strut suspension with coil-over Konis, adjustable ride height, with guess what, Caster/camber plates, that allowed adjustment of both caster and camber. The strut towers were impressively braced across the car and rearward to the firewall. The engine mounts were replaced with a tubular cradle unit that locked everything together and the steering ram was remounted with aluminum bushings for solid steering. Needless to say the moncoque frame was extensively beefed up, all the way out to the door sills with diagonal bracing. This became a stiff car. I got clued in to all this stuff while having Steve Saleen drive my stock Cobra around Seattle Intl Raceway. FOR FIVE LAPS!! I told him to "Go for it, the engine is Bulletproof" and did he ever!?!? I thought we were inside of a beached whale, the guy is a maniac!!! And the car was ridiculous!
Having access to camber was very beneficial in open track work and adding 2.5 degrees (negative) was optimal for smoking the Porches and Vipers. I was running Firestone SZ-50's which were actually built in the Bridgestone factory in Japan. These were equivalent to our Sport Soft tires with a speed limit of 160 mph.
The other thing that I loved doing was the Silver State Classic Series of rallies in Nevada. This is where they block off about 100 miles of PUBLIC ROAD and run the race/rally for about 8 hours. In the main event, the road was a series of straights, linked by corners that could be taken flat out to about 180 mph. Some of the straights were close to 14 miles long!! Shades of Route X! For this event, all that camber would not be required, so I would back off the camber to -0.5 degrees and swing the caster(the top of the struts) back to 9 degrees which is Mercedes country!! This made the car super stable at speed and still alowed decent cornering. Mercedes run a lot of caster because they are made to run well over 100 mph on the German Autobahns. They are not twitchy at speed and neither was my Mustang.
Just in case anybody cares, the rear suspension of my Mustang was also changed with coil-overs overtop of Koni circle track dampers, adjustable ride height of course, and a torque arm from the differential pumpkin to a cross member midships and a panhard bar to anchor the axle laterally made the ass end like a rock when you pushed the back of the car across the axle! Suddenly a Mustang that would not spin out was born!!
I guess the point of this epistle is to emphasise the function and importance of both caster and camber in tuning a race car. It would be my dream that PD could impliment both of these tuning aids in GT-6 as per real life cars.
For me the fun thing about GT-6 is being able to tune without spending a bazillion real dollars and not getting very dirty and greasy at the same time. Oh, and being able to tune in hours instead of months.
Thank you for your attention, Mustangxr
It's actually pretty simple & since it's clear so many think I'm wrong clueless blah blah, I kept very obscure for a reason, this is to see if the big GTP tuners would have the following answer... Not one came through, it's a shame.
Cats about to jump out.
How I use camber and a demo car for proof...
Riding neg camber on the inside front tire helps with cars that oversteer crazy. Like the Ruf YB and X-Bow
many use ballast to cure this and they are adding mass wheel angle tuning will fix
Riding pos cam on the inside through the corner will help cars that understeer a lot and help control under/over balance
So
Pos camb on inside to help cars with understeer
&
Neg camb on the inside to help cars with oversteer.
Proof? Grab a Ruf YB add 5 degrees front and 1.5 in the rear
Want proof?!?!?!?
This is not a tune just a camber demo
Buy a RuF YB
Get Sport Soft Tires
Add the adj suspension
Leave ride height stock

Hit the track, notice the cars front end just doesn't want to hold in the corner just a pita to drive...
Usually ballast to the rescue adding mass for no good reason..
Instead adjust the wheel angles to
Camb
6.0/1.5
Toe
0.35/0.65
I have just demonstrated using neg camber on the front to have my inside front tire ride neg camber in the corner instead of positive as with zero camb setting... This is to help with the cars oversteer...
You can also try
Camb
0.0/0.0
Toe
0.35/0.65
Zero camber It will not be cured of the oversteer it will just oversteer at a slower pace, making longer slides.
Adding the crazy camber to a Ruf Yellowbird changed it from an oversteer nightmare, to understeer yawner... And I could run the brakes tuned to weight even..... Surprise the rear ain't on fire, notice that...
As you can see this reduces oversteer in the front and the rear is still composed holding on well with its -1.5 camb and 4/6 brakes
The reduced oversteer now makes the car much easier to drive.
That is not a Tune, just demonstrating how using camber in the front can help with oversteer. I kept the car very much out of whack and used exaggerated camber up front to illustrate my point.... IF you know how to use camber in the front it's a great tuning tool..
The YB is a beast love it love it love it...
Ketchup for those Feet?
So you tested positive camber in GT6? Have you also tested with different caster angles and wheel widths?Riding pos cam on the inside through the corner will help cars that understeer a lot and help control under/over balance...
...Adding the crazy camber to a Ruf Yellowbird changed it from an oversteer nightmare, to understeer yawner...

Notes :
This is one EPIC REPLICA
So, the TEIN Engineer visited US soil to showcase their latest Super Racing Circuit Coilover Kit for the famous trio ( FR-S, 86 GT and BRZ S ) Their main car for the demo/test was Subaru BRZ S, the car was stock except for the prototype exhaust, stickier extreme performance summer street tire ( Ventus R-S3 - Comfort Soft in GT6 ) wrapping ENKEI RPF1 17 inch wheel, AP Racing Big Brake Kit and the TEIN SRC Coilover Kit.
The TEIN Super Racing Circuit Coilover is able to handle a range of spring rate :
Front : 8kg/mm-12kg/mm
Rear : 10kg/mm-14kg/mm
The Demo/Test car replica above had medium rate - front 10k and rear 12k spring rates and track damper settings as the real test car have.
Here are some suggested damper settings after extensive tuning and testing that will surely enhanced the experience with TEIN SRC Coilover :

When tested at Willow Springs IRL ( not a pro driver ), the car was considerably faster than using stock suspension + factory tires ( same everything else ).
Streets of Willow Springs
1:29.xx stock suspension + tires
1:25.xx Ventus R-S3 + Tein SRC ( GT6 replica target time -Comfort Soft )
Willow Springs International ( Big Willow )
1:38.xx stock suspension
1:36.xx Ventus R-S3 + Tein SRC ( GT6 replica target time -Comfort Soft)
The replica above is able to post similar lap time or even faster in the hand of better driver. Tested in GT6 at both Willow Springs Big and Streets.
My impression : The TEIN SRC gives the BRZ/FR-S/86 GT a great feeling overall, exceptional handling and grip with understeer or oversteer that can be initiated almost at will by the driver.

Literally, hit the road(track), Jack. Test your theories. Side by side. You claim expertise; PROVE IT. Videos or it didn't happen, too.Your making the HUGE assumption they are not However this goes against the theory "wheels go where they are supposed to but do not do what they should""
I am of the impression without understanding camber, how it works, or how to tune it to the corners, it will be IMPOSSIBLE for you to test or tune something you misunderstand...
You guys cant even say HOW its broken and your tuning theories on it are more about Caster than Camber.. Even though Caster Angle called ""CASTER""" it applies a varying measureable amount of camber angle in the corner changing with the steering input.. You all seem to not fully understand the relationship between Caster and Camber... This is a HUGE part of the GTP consensus problem...
Thats a heep of speculation
I call that's twisting facts to support your conclusion....
I can agree with this, except that I have had lap time gains with tiny camber values (0.1-0.3) and what felt like more ultimate grip.Actually, it's called using the facts to reach the speculation.
FACT - Your suggested setting to the Yellow Bird (yes I tried it) leads to a more reactive front, but less adhesive front and rear. That is completely consistent with positive camber. Not at all consistent with negative camber. (BTW, I love the Yellow Bird and the BTR. My favourites for sure and mine are awesome handing cars )
FACT - EVERYONE ELSE has found that camber reduces grip regardless of car, body roll, weight, spring settings, damper settings, roll bars settings, or any other setting or combinations.
FACT - Every element of the tuning menu is listed as positive amounts. Toe, being the one element that has both positive and negative. Negative toe is clearly stated as a negative value (ex -0.1).
FACT - Although the intention is for camber to be negative (as indicated in the heading title in the UI for camber). The numbers shown are in fact positive. There is no "-" before the number as there is with the negative values of toe.
FACT - The UI is flawed. It clearly indicates that the ride height value is INCHES, when we all know that cannot possibly be the case and it is more likely indicating millimeters.
FACT - KW suspension is proudly displayed in the suspension menu. KW's simulations can deal with positive and negative camber. It would then require that the values entered be either positive or negative. I do not know how much of their technology (if any) is in the system. However, if there is any, it would assume positive values are indeed positive.
Based on these facts, I believe that the physics is using the value from the suspension settings without multiplying the value by -1 in order to obtain negative camber.
I also made video games for 20 years and I've seen stuff like this happen plenty.
I can agree with this, except that I have had lap time gains with tiny camber values (0.1-0.3) and what felt like more ultimate grip.
But the fact the values are so small suggests the 10x theory to be true.
I do not know enough about positive camber, and how it can influence handling characteristics, to summarise that what the setting screen is telling us is actually true (we are adding positive camber!).
Yes, you can see lap time gains. Positive camber in the rear will help with rotation. Positive camber in the front will make the vehicle more reactive. I've found the same gains with it which made me believe that it was working. However, the more I looked at it, I found that it was easier to be on a line but I wasn't gaining grip.
The reason I don't support the 1/10 idea is that a value "10" would then have to be -100 degrees of camber and that would make the cars completely undrivable. Testers would have caught that one easily. -90 degrees of camber would make the wheels face the sky. the cars would be incapable of movement.
Was camber the only thing you changed?Results of mine are clear
Laguna GT350 500pp SH
1:39.9 low rear camber 0.3
1:38 after raising up rear camber to 2.2
no assist.
Why?Results of mine are clear
Laguna GT350 500pp SH
1:39.9 low rear camber 0.3
1:38 after raising up rear camber to 2.2
no assist.
So if your crying for lap time results try reading my post before because that's been posted already. Also others have been posting improved times using camber in the other thread..
Why is it those times get ignored or even better, some half understood fact twisting trying to explain it away as less grip must be causing the improvement..
This whole debate has been a joke as far as GTP asking for everything served on a platter while they just post BS or stuff somebody else wrote on a web page and they copy past it as if it's there words.. Do you even realize most of the crap you guys post to prove your point doesn't prove your point at all and most time while it is relative to the subject ITS OFTEN NOT relative to the point being made or refuted...
You can point fingers at me in every post to do this do that prove this prove that but it don't matter to me. There are readers here interesting in the facts about camber in GT, not your suspicions, opinions, or half understood clips you post, while some are quick to pat each other on the back for the great info they copy off somebody who does have a clue... In the end who am I debating, you ? The guy you copy off of, OR an I arguing your interpretation if somebody else explaining something about tuning??? Go get the guy writing the stuff you guys copy, Im sure he and I could have a real convo on tuning....
It's in your hands but are you capable is the question...
You have a demo car to see for yourself obviously blueshift is clueless having not driven the thing evident in his post... It's a DEMO CAR lmfao..
However I apparently gave the front end more control with less grip lmfao vs it swinging uncontrollably with the camber reset to zero, how does that work @ Blueshift?!?!?!? Wait wait, it must be the less grip in the front gives added steering control right???
Ohh you guys really miss the target completely.... 3 wheeling lmfao
I've not seen to many race cars tuned to lift the front tire in every corner... Seriously? Think that is helping it's cornering ability in that corner?
As MCH even said he had to compromise his camb setting (although he mixed up the detail, he tuned the inside, not out ) so he could clip the curb at apex without sacrificing speed on exit. Got him the win. Example of some tracks need a little compromise as all the corners are not the same or a particular corner has character...
What your looking at is an example of tuning to the track as a whole vs just one corner. At certain point along the track it's a compromise. Kinda lame to post 3 wheeling pics like that though, shows a half understanding of what you've been reading in your Goggle quest to twist facts to support your conclusions.
You guys should work for the Show "Ancient Aliens" that shows all about twisting facts to support conclusions...
