Parameters
There are 37 parameters in 6 groups.
Physical Attributes
(A) vehicle identifier
This is used by the vehicles.ide file to identify the handling line of the vehicle.
(B) fMass
This is the weight of the vehicle in kilograms.
(C) fDragMult
This describes the wind resistance of a vehicle
(D) nPercentSubmerged
A percentage of vehicle height in the water before vehicle "floats". So as the vehicle falls into the water, at 85% vehicle height (seemingly the default for road vehicles) it will stop sinking to float for a moment before it sinks (boats excluded).
Value: any percentage expressed as a decimal (eg., 85% = 0.85)

(F) CentreOfMass.y
(G) CentreOfMass.z
