Changing Handling & Speed For Modded Vehicles

This guide is mainly intended for mod users who would like to learn how to change driving behaviour, but also adds info to the Basic Car Modding Guide.

Driving behaviour of each modded vehicle is defined in the .yaml file included with each car mod.

This .yaml file will be somewhere in r6\tweaks\. Some modders put their .yaml files in subfolders with their name or the name of the car whithin the tweaks folder. The .yaml file must be somewhere inside r6\tweaks though.

Some modders also use .tweak files to define the driving behaviour of their cars. This tutorial won't cover these, but the settings within those files use the same names and values as .yaml files. The files are formatted differently and the information presented here must be adapted to the specific format of .tweak files.

Changing Speed

Manually

The engine setup is made up of different sets of values for each gear of the car. These sets of values are usually taken from one of the vanilla cars and then modified. The sets of values are added to the car within the vehEngineData section of the .yaml, which we'll now look at:

Open the .yaml file of a modded car using a text editor like Notepad
Search for vehEngineData
This section might look like this:

  vehEngineData:
    $base: Vehicle.VehicleEngineData_4_SuperSport
    gears:
      - !remove Vehicle.VehicleEngineData_4_SuperSport_inline0
      - !remove Vehicle.VehicleEngineData_4_SuperSport_inline1
      - !remove Vehicle.VehicleEngineData_4_SuperSport_inline2
      - !remove Vehicle.VehicleEngineData_4_SuperSport_inline3
      - !remove Vehicle.VehicleEngineData_4_SuperSport_inline4
      - !remove Vehicle.VehicleEngineData_4_SuperSport_inline5
      - !remove Vehicle.VehicleEngineData_4_SuperSport_inline6
      - !remove Vehicle.VehicleEngineData_4_SuperSport_inline7
      - !append yv_r8_gear_reverse
      - !append yv_r8_gear_1
      - !append yv_r8_gear_2
      - !append yv_r8_gear_3
      - !append yv_r8_gear_4
      - !append yv_r8_gear_5
      - !append yv_r8_gear_6
      - !append yv_r8_gear_7

This car uses Vehicle.VehicleEngineData_4_SuperSport as the $base for its engine setup. This is the Rayfield Caliburn
Vehicle.VehicleEngineData_4_SuperSport contains eight gears, inline0 through inline7
inline0 is the reverse gear, inline7 the seventh gear
The vanilla gears are removed from the modded car in the lines start with - !remove
Custom gears are added to the modded car in the lines that start with - !append
The custom gears are defined further up in the .yaml
Use the search function of your text editor to search for the name of each gear, for example yv_r8_gear_7
It might look like this:

yv_r8_gear_7:
  $base: Vehicle.VehicleEngineData_4_SuperSport_inline7
  maxEngineRPM: 9000
  maxSpeed: 45.75
  minEngineRPM: 4100
  minSpeed: 40.2000008
  torqueMultiplier: 0.205

yv_r8_gear_7: is the "title" of the TweakDB entry for this gear
It uses Vehicle.VehicleEngineData_4_SuperSport_inline7 as its base, this is the seventh gear of the Rayfield Caliburn
The most important values are minSpeed, maxSpeed, and torqueMultiplier
minSpeed defines the minimum speed of each gear
maxSpeed defines the maximum speed of each gear
torqueMultiplier defines how quickly the car goes from minSpeed to maxSpeed
Raising all three values across all gears makes the car go faster

My explanations of each value might not be technically correct. I've arrived at this explanation by changing the values and seeing what happens in-game. Finding a gear setup that feels smooth across all gears requires a lot of trial and error.

You can also change these values live in game using Whip Wizard.

Vanilla Gear Setups

If you don't want to make an entire gear setup from scratch, you can also use an unmodified gear setup from one of the vanilla vehicles. Since we now know how the gear setup works, we can remove the custom setup of the modded car:

Within the vehEngineData section of the .yaml, remove everything but the line that starts with $base:
Feel free to stop here if you like the engine setup of the vanilla car that the modded one is based on
If not, find the name of the TweakDB entry for a vanilla car
Download & install WolvenKit
After starting the program, click on "Continue to editor" in the bottom left corner
Open its Tweak Browser from the right sidebar and wait for it to load
In the search field at the top, enter a keyword of the name of the car
The names of the car within the TweakDB might not line up entirely with what's displayed in-game
If all else fails, search for the car brand such as "Quadra"
In the list on the left, scroll down until you see entries that start with Vehicle.v_
In this example, we'll use the Porsche 911 Turbo
In the list on the right, scroll down until you see vehEngineData
Right click the vehEngineData entry and navigate to "TweakXL > Copy to Clipboard"
Hold down Shift on your keyboard and "Copy to Clipboard" changes to "Copy Name to Clipboard"
Click on "Copy Name to Clipboard"
Now, back in the text editor, replace the name of the gear setup of the original car with the one you've copied.

For example:

vehEngineData:
    $base: Vehicle.VehicleEngineData_4_SuperSport

Would be changed to:

vehEngineData:
    $base: Vehicle.v_sport2_porsche_911turbo_inline0

Here are some of the names for the gear setups of vanilla cars:

Changing handling

Similarly to the engine setup, handling also works by adding handling data from vanilla cars onto modded ones and then overriding that data. Handling is defined in the vehDriveModelData section of each .yaml file. Such a section might look like this:

  vehDriveModelData:
   $base: Vehicle.VehicleDriveModelData_TurboR_VTech
   maxWheelTurnDeg: 55
   wheelTurnMaxAddPerSecond: 100
   wheelTurnMaxSubPerSecond: 140
   chassis_mass: 1200
   total_mass: 1200
   center_of_mass_offset: { x: 0.0, y: 0.0, z: -0.135 }
   wheelSetup:
    $base: Vehicle.v_sport1_rayfield_caliburn_inline1
    backPreset:
      $base: Vehicle.v_sport1_rayfield_caliburn_inline3
      frictionMulLateral: 1.28
      frictionMulLongitudinal: 1.28
      wheelsVerticalOffset: 0
    frontPreset:
      $base: Vehicle.v_sport1_rayfield_caliburn_inline2
      frictionMulLateral: 1.28
      frictionMulLongitudinal: 1.28
      wheelsVerticalOffset: 0

Here, the handling is copied from the Quadra Tubo-R VTech onto the modded car and then modified with custom values.

The three lines that start with $base: work the same way as the engine setup. You can replace the vanilla cars used there with other vanilla cars by following the method outlined above.
maxWheelTurnDeg is the highest angle that the front wheels can turn while steering
wheelTurnMaxAddPerSecond is the speed at which the front wheels turn while steering
wheelTurnMaxSubPerSecondd is the speed at which the front wheels return to their default rotation after steering
All three settings:
- Affect steering sensitivity
- Decrease for lower sensitivity
- Increase for higher sensitivity
frictionMulLateral and frictionMulLongitudinal affect wheel grip
- Decrease for more drift-y handling
- Increase for more grip

My explanations of each value might not be technically correct. I've arrived at this explanation by changing the values and seeing what happens in-game. Finding values that handle well requires a lot of trial and error.

Same as with the engine setup, you can also change these values live in game using Whip Wizard.
