I've seen a video that replace the texture of the map in the pause menu, so you can see the topography of the map. That's an "advantage over other players" because you can see mountains and make a strategy to attack or something, so you are "cheating" in some way.
But a texture for a car, I think, its not a big deal, but remember that you are modding online so you are going against their rules.
I suggest you to wait for rockstar to answer your ticket. If they don't answer contact them on twitter with your ticket number, they answer you right away.
