I installed Koni Str.T struts (and new mounts) over the weekend. Read many good reviews and decided to take a chance on them since they were very reasonably priced. They are just as firm/compliant as the stock Sach/BMW units but with a smoother ride. They soak up bumps in the road better. I'm very happy with them. Also installed tower reinforcement plates.
The install was quite a learning experience. Couple of points, if you get this Koni model be sure to also buy boots because these don't come with new ones. You'll need to compress the springs to fit the fronts up into the towers because they will extend too far and you won't be able to get the bottom of the strut into the knuckle. So this means you need to compress the springs to get them onto the strut and again to install onto the car. I guess I could have removed or loosened the hub but I found it simpler to compress the spring.

Are ZHP FSD's the same as stock E46?
