This is a fictional skin for the Lamborghini Gallardo SL (4k).
Just extract the folder inside the zip file to your Gallardo_SL skin folder.
..usually found here:
"...\Steam\steamapps\common\assettocorsa\content\cars\ks_lamborghini_gallardo_sl_s3\skins"
(Sry for the confusion, the first entry in the version history is the COMPLETE skin and the second entry is just the updated preview plus the screenshots..)
Have fun and leave some feedback if you like
a rating would be amazing..
