Digressive valving gives more damping force at low piston speeds for control in cornering, braking and acceleration, then levels off at higher piston speeds so bumps and potholes are taken more softly. The goal is a car that rides well day to day and stays composed on a track day.\u003c\/p\u003e\u003cp\u003eEvery kit comes with Swift Springs at rates HRD selects for each chassis, 304 stainless steel pillowball bearings, and titanium hardware for the top hat studs and nuts, damping adjustment knobs and pillowball collars.
