Standalone in-game vehicle tuner with presets, dyno reports and instant XML export
The HKN handling editor is a standalone tool that lets you shape the way every car, bike and truck behaves directly inside your FiveM server without ever touching a text file by hand. Instead of editing raw meta values offline and restarting the resource to test them, your developers and trusted staff open a clean interface, drag a slider and feel the difference on the road in real time as they drive.
Because the resource is completely framework agnostic, it drops into any server running ESX, QBCore or a fully custom base with no extra glue code. It is built for performance, sitting idle at a negligible resource cost until someone actually opens the menu, so it never becomes the reason your server hitches during a busy roleplay night when dozens of players are online.
Why this handling editor stands out
The interface is designed for people who tune vehicles all day, with a smart search box, grouped fields and a dyno-style report that clearly shows what each change does to the car.
- Live sliders for acceleration, braking, traction, suspension and centre of mass, all with instant on-road feedback.
- Unlimited preset saving so favourite setups can be recalled for any model in seconds without redoing the work.
- Diagnostic modification report that neatly summarises every adjustment for expertise-style tuning roleplay.
- One-click XML export that writes clean, valid values ready to paste straight into your handling.meta file.
- Multi-language support covering English, Turkish, French, German and more available out of the box.
Built for tuner and racing servers
Whether you run an underground street-racing community or a licensed garage economy, this tool keeps balance firmly in your own hands.
- Permission gating so only mechanics or admins can push handling changes live to the server.
- Fully adjustable config for the menu keybind, allowed jobs and safe default limits.
- Responsive design that scales cleanly across every common in-game resolution.
- No external dependencies at all, keeping installation to a simple drag and start.
- Regular value validation to stop unrealistic or game-breaking numbers slipping through.
The result is a far smoother pipeline for anyone who cares about how cars actually drive, and a happier player base that immediately notices the extra polish on the road. Your team iterates in minutes rather than hours, testing ideas the moment they think of them.
Setup takes only a couple of minutes: extract the folder, add it to your server.cfg and adjust the config to match your job names and keybinds. Explore more options in our scripts catalogue or browse related HUD and UI scripts to round out the experience.
