Hey, I was trying to change the sound of my modded BMW M5

I Searched what sound my BMW is currently using and I found the following: <audioNameHash>SURANO</audioNameHash>

So now I downloaded some .awc engine sound file.

But where is that "SURANO" file and where do I have to copy the .awc file to?

I was searching for over 2h now and couldnt find a solution.

Hey,
So I have watched a few vids of how I install car mods.

But now, when I launch the game with the car mods it just crashes in the loadingscreen after I pressed Story Mode

What I did:

Copied modfolder (bmwi8) into C:\Program Files\Rockstar Games\Grand Theft Auto V\mods\update\x64\dlcpacks
I also added the required line with openIV in C:\Program Files\Rockstar Games\Grand Theft Auto V\mods\update/update.rpf

But now it crashes in the loading screen, when I remove the line in the .rpf and remove the mod-car folder, then it works again.

I DO have scripthookV and simple trainer!

Please help I cant find any helpul information

Using latest version of GTA Rockstar version
