These Koni products make a world of difference in your car's handling and allow you to adjust the stiffness for your driving style. The Koni inserts are assembled into your old strut housings. It is really pretty simple, just a drill and hacksaw or fine-tooth Sawzall needed. The struts come with a knob to adjust.

Works best for high performance street and autocross and track day use. Can be used for smooth Rallycross, but needs more travel and typically wears out fast in rougher Rallycross situations.
