Well, seeing as how only one person in this thread says he's actually had them, how about I give you an experienced opinion of them? Everyone is saying they are shit but not giving reasons as to why.

I personally had them on my S2k for over a year and about 25K miles. The Type R and S2000 models come with MUCH stiffer rates than any of the other setups K Sport makes, so keep that in mind that my review is based on one of these setups. They are 36 way adjustable dampers and trust me that gives you plenty of damper/rebound control compared to any other run of the mill setup. They are also fully adjustable allowing you to set preloads on the springs, and adjusting ride hieght by moving the entire damper up and down. I'm not saying they are in the KW or Showa range but they are good for what they were made for and the price reflects that. I loved them and the awesome sense of control they provided. However, I don't think this setup is for you if you are looking for a softer ride. They are a great affordable setup for the track. I got rid of mine b/c the ride quality finally got to me. One complaint I have with them is for those who love being slammed, K-Sports don't offer much suspension travel when set so low. However, they are not designed to slam your ride. I cut the bump stops and adjusted the damper hieght as best as I could and lived with it. I am currently looking for another setup now, but might end up purchasing K-sports again.

Koni makes a great product, however I personally don't like that they give you only 4 settings of Damper/rebound adjustment. The common Ground control/Koni setup is a great match for the street however. I'm sure with the correct custom spring rate they can be a great track match too, but you will sacrifice ride quality at that point. And this setup also provides TONS of suspension travel at a low ride hieght. Koni offers a lifetime warranty on their products as well.

Hope this helps.
