Arrow KW Sleeve Over Kit Springs

I've done a ton of reading now of reviews on the KW Sleeve Over kit and while most seem to be very happy with it, there's been a few who have said that it results in a bouncy ride (even with EDC).

I would think that any bounciness would be experienced (or not) consistently by everyone with the same cars. Is there a final word on whether it results in bounciness or some other negative handling effects (other than potential early strut failure)?

Would driving in Sport EDC mode cure any potential bounciness?

Please, no suggestions of coilovers or other springs, I know of and am considering those options. I'm only asking for feedback on the KW Sleeve Over springs. Thanks!

First I will say that "bounciness" is some what subjective IMO.

Mine rides nicely with EDC in Sport Plus (two lights, whatever it is). In Comfort (no lights), there is quite a bit of body movement on wavy freeways (bounciness maybe?). Also, with the front all the way down, it will hit the bump stops.

If you track, these will probably make you slower also. I am pretty sure that these are handicapping me on the track.

I've been considering the KW Sleeve Over Kit as well. My car does not have EDC.

Would appreciate feedback as well.

I just finished installing the sleeve kit. I have not noticed any "bounciness" but then again I have not driven much since the install. I will keep notes and report back

I know that the height adjustment doesn't seem like a big deal but it is totally worth it. Firstly, you can tune the stance just right. Second, if your car is multi-purpose like mine (weekend warrior), I raise it up every time I go to the track. It handles better (because the OEM shocks don't like being low) and in case I go off it minimizes the damage.

Thanks for all the replies everyone. And yes, this is one of the reasons I want the sleeve over kit - for height adjustment for the occasional track use.

Seems like bounciness isn't a huge issue with these, with most report none and few reporting maybe just a bit.

Anyone else have any input?

I came from RD Sport springs w/ EDC and they were stiffer than the KW sleeve kit even on comfort mode so the transition made the "bounciness" more prominent, but after some-hundred miles later, I don't even notice it.
