I now have two of their cars. The front wheel arrangement has an independent wheel rotation and suspension. I have not seen this in any of the 1/43 cars except in certain 1/53 scale trucks.
Their independent rotation of the front wheels prevents fishtailing of the car. It looks like a purchased piece and not a 3D print like the car frame.
Has anyone know of a car model with this piece? I'd like to modify my own cars.
