@Xoppi when you scroll to the right when in vehicle options i think you should see something by the lines of engine multiplier. enable that and underneath is the multiplier itself. you can change that up to make the cars really fast. there is also torque multiplier as well which change torque.
I have a problem where i cant load the car using anything. i mainly use addon spawner and it says "couldn't load model" does anyone know whats going on here. i can load other mods juts not this one :(
@Gabbe_144 Sorry dude. Modding is exclusive to PC
@Jackle180 theres a thing called OpenIV which is a software to do all of that. what you have to do is make a folder called "mods" in your main directory of the game. also download scripthook and drag the contents into the main directory of the game. http://www.dev-c.com/gtav/scripthookv/
when in openiv make sure you press "edit mode" that one took me a while to figure out. if you do some googling about how to add mods you will figure out more
