HELP! Please?

I am hosting my own server for my friends and I need some help from this community.

WARNING I am new to this, so please bare with me!!

So, I have vMenu installed and under the vehicles, it appears as though the DLC vehicles are listed, but we can’t spawn them because it says something about “your server is not streaming them” or something like that.

  1. How do i enable these vehicles? Or get them in general?
  2. Also, I would LOVE to get more add-on vehicles, mods, etc. Any recommendations on some packs? And how do I install them on the server?
  3. Does anyone know when the Los Santos Tuner/Car Meet DLC will be available for FiveM?
