FiveM handling.meta Editor

GTA V's handling.meta is the file that controls how every vehicle physically behaves: mass, drag, drive force, brake bias, steering lock, traction curves, suspension stiffness, damage multipliers, and ~70 other parameters. The XML is straightforward but the field names are obscure (fClutchChangeRateScaleUpShift, vecInertiaMultiplier, fTractionSpringDeltaMax) and the realistic value ranges aren't in any in-game help text. Most existing tools are either paid Tebex / Cfx Marketplace scripts ($15-30 in-game UIs) or abandoned web pages with no field documentation. This editor exposes every documented CHandlingData field with a plain-English description, a sensible min/max range from real GTA V vehicles, and a slider you can drag to feel out the value.

Workflow: paste your existing handling.meta into the import box (or pick a preset — Adder for a balanced supercar baseline, Buffalo S for a sedan, Phantom for a heavy-truck cab, Akuma for a sport bike, Voltic for an electric/CVT setup). The parser pulls every documented field out, populates the form, and preserves any SubHandlingData block (CCarHandlingData, CFlyingHandlingData, CBoatHandlingData, CTrailerHandlingData, etc.) untouched on output. Edit anything in the form, watch the right-hand pane update live, copy or download when you're happy.

The editor groups fields into 7 tabs: Mass + Aero (mass, drag, downforce, submersion, center-of-mass offset, inertia multiplier), Drivetrain (drive bias, gears, drive force, drive inertia, clutch shift rates, max flat vel), Brakes + Steering (brake force, brake bias, handbrake, steering lock), Traction (curve max/min/lateral, spring delta, low-speed loss, camber stiffness, traction bias, loss multiplier), Suspension (force, comp/rebound damp, upper/lower limits, raise, bias, anti-roll bar, roll center heights), Damage (collision, weapon, deformation, engine multipliers; petrol + oil volume; consumption rate; seat offsets; monetary value; pop-up light rotation), and Flags (HF_*, MF_*, DF_* bitfields with one-line effect description per flag, plus AIHandling preset).

Every numeric field has live validation hints from real-world Bohemia / Rockstar configs: fInitialDragCoeff is divided by 10000 internally so 5-25 is normal; fInitialDriveMaxFlatVel × 1.32 ≈ real km/h top speed; fTractionBiasFront at exactly 0.0 or 1.0 disables an axle's tires entirely; fSuspensionForce × wheels × |fSuspensionLowerLimit| should exceed 1.0 or the suspension never settles. Where GTAMods Wiki and FiveM community references disagree, we cite the most-tested interpretation and flag it as disputed.

Bitfield flags are the editor's biggest time-saver. handling.meta flags are stored as a hex string ("440010") and even experienced modders have to sit down and OR-together the bits by hand. Here you just check the boxes — HF_NO_HANDBRAKE, HF_HAS_RALLY_TYRES, MF_DOUBLE_REAR_WHEELS, DF_BONNET — and the hex string updates live. Every flag has a one-sentence effect description from GTAMods. AIHandling is exposed as a 4-option select (AVERAGE / SPORTS_CAR / TRUCK / CRAP — those are the only valid values, despite community lists claiming more).

Pairs with the FiveM Vehicles Database on this site (look up real handling values from any of GTA V's 764 base vehicles), the JOAAT Hash generator (for adding your edited car's handlingName to job/whitelist scripts), and the fxmanifest.lua Builder (to ship your custom handling.meta as a streamed resource).
