See, there we had it again, basically Kubby showed you something you could find by searching

haha!
Anyway man, Badges can't be made properly right now, only with a slight hack Pyrlix and I did a while ago when making the Znopresk badge.
@Jakgoe: The letters wont work, as all badges align to the middle. You would either need to add them as exhausts, or wait for the devs to implement a custom badge system where you can type in characters, select a font and then than badge gets placed on the car when you click done. All they then need is for it to freely move around. Not high on the prioritylist, but I would personally love this!
