This pack is part of the LaFerrari FXX K skins pack.
You can find the rest here: http://www.racedepartment.com/downloads/laferrari-fxx-k-pack.5569
So the pack includes 4 different FXX K skins stiles variants:
- Blue (Fallout 4 theme, v1.2)
- Blue (yellow stripes, v1.2)
- Blue (black stripes, v1.2)
And relative "n/n" versions, which means "no number" 'cause they show no racing number.
Except "Fallout 4 theme" skin: it has no "n/n" version.
