1. Use OpenIV to install the mod. If you don't have OpenIV, you can download it from this link. - https://openiv.com/
2. Using OpenIV, navigate to Grand Theft Auto V\mods\x64e.rpf\levels\gta5\vehicles.rpf\ or Grand Theft Auto V\x64e.rpf\levels\gta5\vehicles.rpf\
3. Drag and drop the files to Open IV.
4. For working dials, liveries, hands on steering wheel as well as better handling, open Handling-Meta.txt, Vehicles-Meta.txt and Carvariations-meta.txt and follow the instructions.
5. Play the game. Enjoy

Extra Note:
1. If you have knowledge on working with textures files, you can change the Livery. You can use the included PSD file for reference. Make sure you put the AOMap above your livery and apply Multiply Blend Mode in Photoshop.
2. I'd really love to see your vids. I'd really appreciate if I see some credits or a link back to my channel. Thanks a bunch.
3. Don't forget to edit Vehicles and Handling meta for a very good experience :D
