Physics Swapping physics and driving behaviour

[seamount0]

Hi all
I have read tutorials about how to swap physics between two cars.
I did it and it works ... but; the car I modified does not have the same behaviour 100%; is it normal (with the same setup) ?
I thought that afterwards they should behave 100% identical, ... or not ?
Or there are other features "not swappable" that make the two cars have little or large driving difference ?

The only other differences would be user-created stuff, like if you save a default setup or change the ffb multiplier on one of them, swapping physics doesn't affect those.

ok thank you

may I ask you what are and mean the INERTIA parameters in CAR.INI ?
example:
...
TOTALMASS=620
INERTIA=1.3,0.81,3.640
...

Please, define "swap". What did you do exactly?

I changed all the "physics" files and parameters of a car, copying in it all the physics files of another one

You "changed all the "physics" files and parameters of a car"?

As per formula_k's car.ini:

INERTIA=1.9,0.8,3.4 ; Car polar inertia. Calculated from the car dimensions. Start with the generic width,height,length and modify accordingly to the car's configuration.

Think of it as a big box that surrounds the car and is defined by the dimensions X,Y,Z at "INERTIA=" and that has the mass of the value defined at "TOTALMASS="

INERTIA in meters
TOTALMASS in kg
