To be completely honest, you should get into skins, not configurations. Configurations have been done to death a bit and new skin packs are not always received with much enthusiasm. However, if you make skins, there is generally more area for customization, and if you make a quality skin, it may be accepted better than a configuration pack. Skin tutorials: If you still want to do configs though, these should be helpful: Packing Config creation By the way, there have already been three threads like this, so if you need more info, just look through community creation and the WIKI for help. Good luck, I look forward to having another member of the mod community.
A good config mod should also include some deeper modifications, not just swapping some parts out, everybody can do that ingame: http://www.beamng.com/threads/tutorial-vehicle-performance-and-components-modification-simple.4261/ Good luck!
