I was considering the KW sleeve-over kit. However, after talking to a couple of vendors that sell this kit I decided against it because I was told unless you use the sport EDC setting the car is under-damped and the ride bouncy. I have no first hand experience but if that's true then it seems getting a sleeve-over to maintain EDC functionality is just not worth it.
Not sure if you'll run into the same issues with EDC damping and lowering springs or if it's the spring rate of the KW sleeve-over that's the problem? Again, no personal experience, just what I've been told...
