For those of you who have the factory sunshade in your sedans or coupes, this is something you should consider doing as the slider clios are made of plastic and will eventually fail.
Since I will be retrofitting this option into my ZHP with a sunshade assembly from a 1999 BMW sedan on its way to me, I have decided to purchase this repair kit and do the repairs preemptively. The only problem I would have from my rear sunshade assembly, if ever, will be the motor failing so I will order the motor assembly separately and put it aside as spares in the event I have this failure.
As time continues, E46 parts such as the rear sunshade and components for it will become expensive or NLA so that is why I source some parts.

EDIT: (26JAN22) this kit was installed on my rear sunshade assembly today.
