Live-tune vehicles with a sleek glass UI. Adjust handling, brakes, suspension, traction, and physics — and feel changes instantly while driving.

What it does

A split interface puts Telemetry (left) and the Editor (right) side-by-side. Edit with plain-English labels + tooltips, lock the camera (drive stays active), and export a ready-to-paste handling.meta. Load built-in presets (Drift, Grip, Rally, Drag) or your own, including optional engine sound swaps.

Once you update the preset file run again the command /presetlist, 

Highlights

• Get started: add the resource and run /openhandling.
