Vehicle Handling Modifications
Understanding Handling Files
Handling files (handling.meta) control how vehicles behave in the game, including physics, performance, and driving characteristics.
Key Parameters
- Mass - Vehicle weight and physics
- Dimensions - Size and center of mass
- Transmission - Gear ratios and speeds
- Suspension - Height and behavior
- Traction - Grip and handling
Prerequisites
- OpenIV with ASI Loader
- Basic understanding of vehicle physics
- Text editor (Notepad++ recommended)
- Backup of original handling files
Editing Process
-
Locate Handling File
Navigate to update.rpf/common/data/handling.meta in OpenIV
-
Create Working Copy
Use "Copy to mods folder" before making any changes
-
Edit Parameters
Modify values carefully, keeping track of changes
-
Test Changes
Launch game and test vehicle behavior
Common Modifications
Performance Upgrades
- fDriveInertia - Engine acceleration
- fInitialDriveMaxFlatVel - Top speed
- fTractionCurveMax - Maximum grip
- fBrakeForce - Braking power
Handling Adjustments
- fTractionCurveLateral - Cornering grip
- fSuspensionRaise - Ride height
- fRollCentreHeight - Body roll
- fLowSpeedTractionLossMult - Low speed handling
Best Practices
- Make small changes incrementally
- Keep notes of original values
- Test thoroughly after each change
- Consider physics realism
- Backup modified files
Troubleshooting
Vehicle Instability
Check suspension and traction values for realistic ranges
Poor Performance
Verify engine and transmission parameters are properly set
Game Crashes
Ensure handling.meta syntax is correct and file structure is maintained
