If you look at the very top of the damper, there is a threaded bar that goes into the top mount, and is secured by a nut. Posher dampers come with a wider diameter threaded bit, and the top mounts have bigger bearings - they are telling you that you can’t mix the OEM size damper with the top mounts that accept a larger diameter.
I don’t know the kw range but I presume the club sport are more track focused and have the larger diameter threaded bit and the v3 is the smaller size. As above, any of the third post top mounts that are compatible with OEM dampers will do what you need.
