Hello,

before you start to edit your files, i recommend this link: http://openiv.com/?p=1132
How to use OpenIV “mods” folder and keep your original GTA V files safe.

<-------------------------Advanced Installation Guide:----------------------------------->

Create a mods folder in your GTA5 directory, copy the x64i.rpf and put it in the mods folder. (needed for Bodyykit)
copy the x64e.rpf and put it in the mods folder. (needed for Bodyykit&BMW M3GTR)

Done! Now you can follow the Instruction descriptions and install all the modifications.
The OpenIV.ASI & the ASI Loader + files in the GTA5 main directory must be installed to run this mod!
