Need to be careful with too much rigidity with the front swaybar. There needs to be some flex somewhere in the assembly. The control arms and the sway bar pivot in different planes, so the geometry of the swaybar rotation and the control arm movement starts to diverge when the suspension is pushed thru its range of motion. So something needs to flex. With the factory rubber bushing and the the single supports, there is plenty of flex, maybe too much. If you use solid bushings and the triangulated brace, there is no more designed flex in the system, so something may eventually break.
I use the triangulated braces, but leave all the rubber bushing in place. I have not had any issues with that configuration.

There might be an issue if the rest of the front suspension is stock and worn and only the sway bar is really stiff as the body roll will be more significant and something will have to give.

Good that you have not had a problem. Hopefully there is no issue. I made my comments based on a casual observation of the swaybar and control arm geometry, and the recollection of other posts (not only this thread), showing occasional failures of sway bar mounts/brackets/links with combinations of delrin bushings and triangulating brackets.
I have not checked on availability of the unique clubsport/cup suspension parts in several years. I still have a couple spares, and have a mix of cup and aftermarket bits (KMR and RE) on my cars. The rubber bushings for the 30mm front and 21mm rear cup swaybars are still available, as the 30mm is the same as the production 968 M030 parts, and the 21mm bushings are the same as for some 911 swaybars.
