Handling Pro

Adjust GTA V’s underlying handling values and test the result through the editor’s real-time preview. Additional handling logic helps previews match the eventual exported file. Values that cannot be previewed in real time are clearly identified, so you know when an export is needed.

Learn as you tune. Impactful properties are marked Useful, while Help explains what a value does, recommended ranges and other practical details. Search for a property or filter by category to focus on the part of the vehicle you want to change.

Start with familiar vehicle characteristics such as acceleration, gearbox, suspension, traction and downforce. Choose from organised presets to improve a vehicle’s handling without working through every underlying value. You can still inspect the changes and move into advanced editing when you need finer control.

Compare your changes on the road with speed, gear, top measured speed, acceleration graphing and timings including 0–60, 0–100 and quarter-mile runs. Previous and current tests appear together so you can see what changed. The timing tool also works independently of the handling editor and supports job restrictions.

Explore the extra vehicle properties hidden in GTA V’s handling flags, including on addon vehicles. The visual editor names each flag and explains known behaviour, giving you a clearer alternative to editing hexadecimal values by hand. Preview supported changes or export the resulting hex value.

Save work in progress as a named profile, then return to it later or share it with other people who have editor access. Search saved profiles, see the original vehicle and creator, and load a setup into the editor to keep working.

Export a handling.meta XML file to make a setup the default for a vehicle model, or apply it directly in game. Save handling to the database for a particular vehicle or model so it is reapplied when the vehicle spawns again, including after leaving a garage.

Work with vehicles already tuned by JG Mechanic. Choose whether to edit the current handling, ignore servicing effects or start from base handling, with each option explained before you begin. The exporter can also generate JG Mechanic tuning configuration for custom parts.

Handling changes use OneSync Infinity state bags to stay synchronised with other players. The script is designed to keep that shared driving experience efficient, whether you are testing a setup or applying it across your server.
