This model is part of the Race Car set I will be adding to RAD. The set can also be downloaded here one by one as I list them, for free. Or you can wait to get them in RAD free.
Again, this model includes the UV work and a Direct X model. You can use Assimp to convert the model for Unity or Unreal FBX use. I will link the Assimp download below.
