The rear wheels of the 406s turn in a corner

Hi guys, I wanted to get information about the rear suspension structure of the 406. I learned that the 406s contributed to the grip by turning a little bit of the rear wheels during cornering. This is really impressive. What are the technical details of it?

I didn't know it was in the 406s
prelude and rover also know that the rear wheels turn like you said
but it doesn't contribute to x2 shape in terms of handling

This system is not as active as a honda or rover. There are no angles as big as it can be seen. It is only because of the flexible connections that the wheels want to turn in the direction of the bend during cornering, but I am curious about the technical details.
