# Handling

> Change the driving values of an emergency vehicle, field by field, from the stock handling.

The **Handling** section lists the car's handling values. Each field starts at the stock value, and a field you change shows a button with the stock value to restore it.

![Handling section with grouped fields and reset-to-stock buttons on changed ones](https://mintcdn.com/rageon/TCzaS11pSGz1CPPK/images/vehicles/evs-handling.webp?fit=max\&auto=format\&n=TCzaS11pSGz1CPPK\&q=85\&s=a72a281933e1bb8fed89b1a5b2f58d3b)

Handling with changed fields and the reset buttons.

## Change a value

Open **Handling** and edit the field. The orange badge on the section counts the changed fields. Click the stock-value button of a field (**Reset … to stock**) to restore it, or **Reset everything to stock** to drop all changes.

Fields are grouped as **Mass and damage**, **Engine and gearbox**, **Brakes**, **Steering and traction**, **Suspension**, and **Other**. Each has the game's own name, such as `fMass` or `fBrakeForce`. Fields starting with `n` take whole numbers.

| Field | Effect |
| - | - |
| `fMass` | Vehicle mass, in kilograms. |
| `fInitialDriveForce` | Engine force: the higher, the faster the vehicle accelerates. |
| `fInitialDriveMaxFlatVel` | Top speed on flat ground. |
| `fBrakeForce` | Brake force: the higher, the shorter the braking distance. |
| `fSuspensionRaise` | Suspension height, in meters: positive raises, negative lowers. |

The stage does not simulate handling. Export the project and drive the vehicle on your server to check the result.

## Shared handling

With **Changes the game model**, several vehicles can share one `handlingId`, so your changes also affect those vehicles. **New model** exports a separate handling entry.

![Handling section with a warning that the handling is also used by other vehicles](https://mintcdn.com/rageon/TCzaS11pSGz1CPPK/images/vehicles/evs-handling-shared.webp?fit=max\&auto=format\&n=TCzaS11pSGz1CPPK\&q=85\&s=0d87565eb9a2d163580460df867afbd7)

A handling shared with other models.

With **Changes the game model**, the section lists the other models that use the same handling. If you do not want to change them, use **New model**.

## Fields the car does not have

If a vehicle carries a field that the car's stock handling does not have, the section shows it in red under **Fields the stock handling does not have**. The export rejects the model while those fields remain. Click **Remove** on each one.

## Troubleshooting

> **The stock handling of "…" doesn't have the field "…" that "…" changes.**
>
> Click **Remove** on the field in the red group of **Handling**.

> **Handling … is also used by …. Whatever you change here applies to them.**
>
> This is a warning. Accept it, or use **New model** instead.

> **Reading the handling of police3…**
>
> The game files are loading. The fields appear when it ends.

> **The handling of … is read when the GTA sources are ready.**
>
> Wait until the game files finish loading.

> **Could not read the handling of …: …**
>
> Rageon could not read the car. Check that the car is in your game files.
