How to raise the speed limit in GMod

Arguments

speedRequired

Maximum speed per axis in units per second.

What it does

Caps the speed of players and thrown or falling objects on each axis. Raise it for fast vehicle or rocket builds, but very high values can make physics unstable.

The game's own description: Maximum speed any ballistically moving object is allowed to attain per axis.

Run it on your server

On a SLASHPLAY server, type it in the Console tab of the server page; the reply shows right under it. A value set there lasts until the server restarts. To keep it, add the line to garrysmod/cfg/server.cfg. New to this? Start a GMod server first.
