Pacejka again

[NaN]

Some might have noticed it. Since the camber calculation fix the F1-02 tends to drift to the right.

Example
1. front left: 10deg slip angle and 5deg camber results in 4877N lateral force
2. front right: -10deg slip angle and -5deg camber results in -5790N lateral force
3. front right: -10deg slip angle and 5deg camber results in -4877N lateral force

In the first and second line both wheels inclined against movement direction generate different lateral force magnitudes, implies that it would make a difference whether the left or right side of the wheel is inclined against heading direction.

In the third line the right wheel inclined towards heading direction generates the same lateral force magnitude as the opposing left wheel. I would expect it to generate less lateral grip. A hint that the camber sign is somehow related to slip angle sign?

I am using the following coordinate system: http://ti.mb.fh-osnabrueck.de/adamshelp/..._coord.htm

I am wondering if pacejka is restricted(valid only) to the upper right quadrant(positive values). Or is it a parameters issue or something else?

Any ideas, insights are very welcomed.
