I'm not sure what can be done about LOD3, skin mapping is as tightly packed as possible.
Lights not supposed to work, they don't on tinted headlights config on reaper as well. I might make them work once night update comes but really not in a rush, it's designed to work with extra light. I could make them work with main lights but then there won't be no main lights as an option.
Best i can do is this, you are not supposed to see it from up close anyway and if you do, it's not gonna be accurate either way because of tris limit. Also the reason it has the shape it has is because front and rear wheel likes to clip into walls and other objects and send you flying.
