It looks like you are asking how to write a proper post about downloading the BeamNG.drive v0.18 update.

: To enhance the 0.18 era or modern versions, players recommend: CK Graphics Settings Mod Dynamic Skybox for photorealistic skies and weather. Tyre Wear and Thermals mod

Part 6: Is 0.18 Better Than the Current Version?

Let’s be realistic.

The only safe, "better" way to download version 0.18 is through official channels using Steam’s Branches feature.
