This is my list of the best mods you can find on GTA IV in my opinion.
This list is strictly only based on my own tastes, there might be better mods for your tastes, but i’m just sharing what I like and what you should try
Realistic Handling by Killatomate
Definitely the best handling mod ever made.
I use this mod since its creation and it’s been years I use it. Totally satisfied. Use it with 300% damage and enjoy driving again in IV 😉
Iron Man IV by H1vltg3 and JulioNIB
One of the first mods that was drastically changing the gameplay and contained new animations.
Very fun to play, works on every patch.
Better headlights by Mr.Poher
You MUST use this mod, seriously. I use it on iCEnhancer 3.0 video. It’s very very good. Makes the car headlights so much better.
Realism Series by CES
Just look at this link… just look at it !
He probably made the best ambient sounds possible for IV, the rain and explosions are a must-have.
I’ll add more when I remember which ones are cool, later
But you already have a cool list here.
Cheers and have fun !
