So what's that mean? Well, here's how a set of Koni's would improve the car vs. stock dampers.

It'll ride better, less harsh. The rear will stay much more planted to the ground and just be a whole lot less jumpy and nervous and more stable. Those are two of the biggest complaints many have. But that's not all. While shock damping does not control how much body roll you get, it directly controls how fast the roll is generated. Better damping (and the fact you can adjust it) allows the car roll slower, and actually change direction faster. And the other thing that Koni's help with is the light feeling as the speed climbs. Again, better damping makes for a more taut and secure car.

The thing that makes German cars drive so well? Much better OE dampers than what American cars have.
