Trying to decide between the Cusco 16mm rear sway bar or the rear sway bar kit from the Prius Plus pkg. My understanding is that the Cusco is a 16mm bar that mounts directly to the shocks and does not use end links. I am unsure of the pros/cons of not using the end links, but I have yet to see an OE rear sway bar not use end links. From the trdsparks page for the xB's TRD rear sway bar, I did read the following: "OEM style ball links allow the beam axle to flex as the factory intended for toe and camber change during heavy cornering." So, I presume that the end links may be important so that the toe correcting bushings can do their job? If someone can comment on this I would appreciate it. The rear sway bar kit from the Prius Plus Pkg is unknown as far as the size, but my understanding is that the one for the xB is 22m? Price is the same for both...about $300 shipped with the hardware kit. Thanks.
