ERROR: Couldn't get parameter "wheel.fl.arm"... an

I'd have to test it to exclude other sources. But to give you an example:
CS.car:

Code:

# these are used to calculate the weight distribution and balance
[particle-00]
mass = 60.0
position = 0.1, 0.5, -0.45

[particle-01]
mass = 130.0
position = 0.4, -1.07, 0.1

[particle-02]
mass = 130.0
position = -0.4, -1.07, 0.1

[particle-03]
mass = 215.0
position = 0.4, 1.09, 0.0

[particle-04]
mass = 215.0
position = -0.4, 1.09, 0.0

690kg mass at/above the height of the door handles of the car.
