Yes, this is Racer in all it's beauty.
Tracks are Fernstone by snowball918 and Speedest2 by some1.
The baking I am doing kind of works like a normal map. Only that I only use black and white as colours for negative and positive z direction. So where the normals point up, the map is white, and black where they point down. The rest is a matter of using blender's procedural texture baker.
