This function is used to change the handling data of a vehicle.

Note

For functionality reasons, suspension modification is disabled on monster trucks, trains, boats and trailers. Additionally, helicopters are not affected by custom handling. The vehicle-on-wheels handling does not affect planes when they are on the ground either. For more information on this, see issue 2426

Caution

To change handling values of aircraft like maxVelocity , you must first set setAircraftMaxVelocity .

Syntax
