Simple little script that checks vehicle handling files and gives it a class and ranking. Kinda like how it works in Forza. Takes acceleration, speed, handling, braking and drivetrain into account. You can easily customize the weights of each aspect and how much they add to the final performance score.
The script comes with a console command (/checkscore) and a QB-phone app. Also instructions how to install a simple version into QB-racing (Our version of QB-racing, that has class based races can be found in our discord, links on GitHub).
And no, we don’t know ESX. Sorry 
Phone app
