Correct, I forgot this detail because I had already installed the tree before.
Inside the 'dragstrip_new' folder comes a custom tree with the name 'baller5' is the same as the link above but personalized with the skin '1320 video'.
To use this, you must change the client.lua on line number 3 where it says: local vehicleName = GetHashKey("ProTree")
For the baller5 haskey. But this step is optional.
Correct installation: You need to start 3 folders. 1st dragtrack;
2nd dragstrip_new;
and the 3rd with only the files client.lua, config.lua, fxmanifest.lua, server.
The files that come loose in the folder refer only to the tree, so they must be started separately. Sorry for my bad English, I'm Brazilian.
