I agree. I had them on a Camry and it was really bouncy no matter how well it was adjusted. But this can be solved with better spring rates. Swift make replacement springs with a better rate that will help a great deal.I heard the same thing in the accord world. That is why I went with Megan Racing coilovers. And yes Megan Racing are kind of stiff but never failed on my. BUT like I said before there are a few here that have ksport and love them.
I honestly think it depends on the vehicle, the price and the installer/driver.
