Install:

1:Copy the "update" folder to 
"Grand Theft Auto V\mods\"

2:If you haven't done it yet, copy the file 
"Grand Theft Auto V\update\update.rpf"
to the mods folder

3:Open the file 
"Grand Theft Auto V\mods\update\update.rpf\common\data\dlclist.xml" 
then use notepad to edit it and add the following line

		<item>dlcpacks:\rx7asuka\</item>

Save it and use OpenIV to replace the original one

OPTIONAL(If you have a lot of car mods or if the game crashes)
5:Use a modded "gameconfig.xml" file


You can use the Simple Native Trainer to manually spawn it using the name "rx7asuka".

IMPORTANT
The lights id value used is "697" so, if you use another mod which uses the same number, you should edit it in both carcols.meta and carvariations.meta for this mod or the other.
