Forgot to mention, I was on the banking with the right-side higher. Camber on the right being -1.4 more negative at the front compared to the left and -0.9 at the rear.
Keep in mind that the angle that is important for grip calculation is the mean angle of the tire surface to the mean angle of the tarmac it is touching.
I think we have 2 sets of angles here.
- Camber = your definition is correct, it should be with respect to the vehicle
- Angle shown in telemetry = angle of the wheel wrt to the track > this is the angle that I was making reference to
