In this video, I show you how to mod GTA 5 PC in 3 easy steps for 2025—simple, safe, and beginner-friendly. I keep it focused on what actually matters: first I set up the basic mod files you need so your game is ready for modding. Then I move to the “must-have” setup part—OpenIV + a proper gameconfig—because this is where most beginners mess up and end up with crashes or infinite loading. After that, I show you how to add cars the right way, so you’re not just downloading vehicles and hoping they work. I also explain how I test mods safely before going all-in, so you can catch issues early and avoid breaking your main GTA 5 folder. This guide is meant for GTA 5 PC Legacy Edition, and if you follow the steps in order, you’ll have a clean modding base you can build on—cars, graphics, trainers, and more—without constant errors.
