I like the KW clubsports a lot! They work really well. Now that I have set them three clicks softer for bump/rebound all the way around the car is less jarring over bumps. What KW recommends is a little too stiff, especially if you have stiffer other suspension parts installed.
The only downside is how you adjust the rebound setting. Since the adjustment is done through the top of the shock then the shocks have to be removed to be adjusted. The PSI raceline coilovers are adjusted a lot easier by turning an adjuster wheel on the side of the shock. If you are going to play which shock settings like something that WestWest would do then I recommend that you get the PSI raceline.
I ordered the KW clubsports a little before the PSI raceline came out. 91GL at Prime Motoring hooked me up with a great price on the KW clubsports.
