It could be Normals or it could be wheel alignment and missing wheel LOD nodes. Having looked at both cars in OpenIV, I noticed they both have abnormal positioning. The wheel must be parented to wheel_lf and also wheelmesh_lf node (LOD node) Also they must be in the same place as wheel_lf. The wheel creates a shadow horizontal from it's node which you can see in almost every car mod around the foot well or even on seats. depending on how low the vehicle is. So it is my guess it's a fault with the wheels.
