How to "convert" your Stadium² car to Tmnf Skidmarks?

[jayten]

Hello guys of the community

I've been stuck with this for a while but i'm not sure how to convert my car to tmnf skidmarks.
I mean by this that it has 2 (actually 4 but 2 visible) lines behind the car when SpeedDrifting(sd) instead of the normally 3 lines.

Whenever i place the skidmarks file in to the skin zip, it mirrors the skin completely which is kinda annoying and doesn't show the actual skin i wanna use, how do i do this without actually mirroring the skin?

Thanks

I'm also not sure if this the right place..
