How to Adjust handling Local Car Vehicles? esx framework

You can overwrite the handling meta files by streaming your own custom ones. You will need to get the original handling files that you want to overwrite, most can be found here, otherwise you will need to use OpenIV to find the handling files yourself.

Then make a new resources with an fxmanifest with the following:

fx_version 'cerulean'
game 'gta5'
lua54 'yes'

files {
    'handling.meta',
}

data_file 'HANDLING_FILE' 'handling.meta'

Place the handling file into the resource and you should be good to go. If you need any help let me know. Happy coding !
