Restricting the SCars tab on my server

Hey, I need help on how to restrict the SCars tab on my server; to a certain group e.g. Superadmin or Owner.



You can’t restrict users from opening the tab, but you can restrict them from spawning the cars

How do i do that?

ENT.Spawnable		    =  false         
ENT.AdminSpawnable	    =  true

Thanks, do i add that some where? or is it already in a file? if so which one?
