Is the metal of the spring plate really designed to flex?

The Weissach-effect is suppose to add toe-in under braking.

Let's assume the spring plate member is supposed to flex. Any flexing of the metal of the spring plate wouldn't add toe-in because that member is never longer than when it is perfectly straight. And flexing would shorten the length of the member and reduce toe-in.


The RS-spec bushing is the outer bushing in the cast trailing arm. This RS arm (Porsche never sold the bushing by itself) is NLA and that's why Ninemeister worked with Powerflex to engineer their poly bushing kit for the rear trailing arm to mimic the stiffness of the RS piece.
