If the theory does show some merit then I would be inclined to believe that camber was working backwards, instead of adding negative camber the physics engine is interpreting the adjustment as adding positive camber perhaps
This thought has been brought up very early in the GT6 days already. I believed it prior to the 1.09 update, but not anymore.
One thing I am wondering is if people are taking into account the new physics model? I get the feeling that many are comparing to how camber worked in GT5 and are expecting to use the same or similar numbers in GT6. That would be a mistake right off the bat since GT6 now includes tire sidewall flex, which GT5 never had.
Camber is supposed to work in the game the same as it does in real life, I don't dispute that and am not arguing that. This does not mean however that the numbers used will work the same. My findings and personal impressions are that when comparing to GT5, I am using numbers that are roughly half of what I used in GT5.
For example, in GT5 my basic starting point was always around 2.4 front and 2.0 rear. I find I am now ending up somewhere around 1.2 front and 0.8 rear for most cars (give or take a few decimals).
This shouldn't come as a surprise to anyone, as I found early on that the same was true for spring rates. I found out very quickly that GT6 used different spring rates from what I would have used on the same car in GT5. My cars in GT6 felt better on "softer" spring settings, meaning lower numbers than what I had in GT5.
I think the first thing everyone needs to do is essentially forget about GT5 and look at this as a completely different game. I wouldn't expect a setup from GTR2 to feel exactly the same on the same car in Project Cars, so why should we expect it when moving from GT5 to GT6? One of the main pieces of promotional material from PD about GT6 was the "All new physics model".
I am not claiming to be right, and I am not claiming that anything is proven. More data and more testing will confirm or refute any and all theories. I am only stating that based on my personal findings ( as posted yesterday) and very subjective "feel" of the cars, I am starting to believe that camber does work as it should. I think what we are now dealing with is more an issue of expectations and preconceptions.
Purely one man's opinion......
