Actually, you can just specify the folder when extracting! Oha!
But still, its a PITA when people do things backasswards. Such as making a car standalone GTR2 style, but not specifying. I've got about 20 unused skins because they need to go into the teams folder rather than custom skins folder.
Anychance of seeing this car with a standard Number Plate/Number? My Z4 needs a playmate to beat down!
It's a great feature, USE IT!
