I had the KW-V3's on my 987 CS for a few years and was very happy with them, and they wear down pretty good (+/- 50k..) before you have to rebuilt them, and if I remember correctly the minimum lowering height was about 1.2 or 1.5" .. I am not looking for lowering more that 1.5"
I no longer have the 987 and the coilovers are not compatible with the 981 chassis therefore I sold the freshly rebuilt KW's and just looking for other alternatives.
The cost of the JRZ's are not much more than the KW's but according to JRZ you should rebuild them around the 20k miles mark which is almost 1/2 of the miles required for the KW's (the cost for rebuild is $750 for the KW's and $900 for the JRZ's) however, I believe that the JRZ's are superior than the KW's for track use.
My intended use will be mostly street driven car with the occasional track day, that is after addressing the 981 cooling with the center radiator to help cooling on the PDK..
You would be the first person that will share (with me) some comparison on both KW's & Ohlins, thank you in advance.

The primary difference is in the valving of the Ohlins and adjustability. The DPV valve acts like a blow off on the street, so sharp bumps that you thought would be jarring are handled really well. I'm amazed at how compliant they are for coilovers that have 400/462lb springs f/r. While it's hard to directly compare to the TT, the Ohlins have a much better ride overall, no matter how I would have adjusted the KW's. If you are looking just for a track shock, then JRZ's are a good way to go, but there are also lots of other good choices.
Lastly, KW uses injection molded pieces on there show for spring perch etc. They are also an odd size as are there springs. So if you want to change springs - you have to change all the hardware. I did have one spring perch crack.
IF you are using on a car that will see a lot of miles on the street, I just don't see how you can go wrong with the Ohlins.
They are also intended for the street, so seals and construction are more on the street side than the track.
