I ran the Koni yellows for years, but just removed them to try the Koni red Special Actives. I just felt the Koni Yellows we're a little boot to stiff and harsh, even running them at full soft all the time. And I was on stock springs, aftermarket sway bars. On certain roads and situations they were great, but I'm in the DC/ Maryland area now and the roads aren't always in the best of shape. That said, I have the Koni yellows listed on fb market place for a fraction of the cost of a new set. If anyone's interested in them let me know.
