Individually Height Adjustable ST XA Coilover kits deliver precise adjustment to your ride height and look of your car. We manufacture the adjustable spring perch made of durable and friction-optimized polyamide composite material with a stainless steel insert. Thanks to the composite material corrosion is prevented between the strut and perch ensuring long lasting height adjustability while the stainless steel insert provides strength and confidence!
Control The Details More control of the driving dynamics thanks to adjustable KW rebound technology. ST XA Coilovers come preset to our factory recommended damper settings, the same configuration we test them at on our KW shock dynos before they go into your box. The 18 distinct clicks of adjustable rebound damping allow you to refine the driving dynamics with a simple turn of the adjustment knob. Each kit includes a detailed damper setup manual making it easy to reset to our recommended setting at any time. Whether your preference is comfort, sportiness, or something in between; ST XA puts the finer details of the driving dynamics in your hands.
Closed Rebound Stage - Sporty, tight and maximized performance Turning the adjustment knob to the right, you increase the rebound force and achieve tighter handling. High rebound forces (closed rebound) improve the handling response, this is especially noticeable on the front axle; the response is a direct and unadulterated sporty experience. This closed rebound stage is ideal if you enjoy spirited drives, long curved banks, canyon carving, and more.
Characteristics at a closed rebound stage:
More direct steering
Pitch and roll movements of body are greatly reduced
Opened Rebound Stage - Retained comfort with added sportiness Turning the adjustment knob to the left your ST Coilover suspension will provide a much smoother ride and improved ride comfort compared to standard shocks and lowering springs. This is ideal when driving on uneven and rough roads by helping to absorb road frequencies. The opened rebound stage takes ride comfort to the next level.
Characteristics at opened rebound stage:
Increased rolling comfort
More driving comfort
Galvanized steel struts, low friction materials with layers of protection Galvanized zinc coated steel struts optimize corrosion protection for long lasting use. We add a dust protection system to prevent unwanted dirt and particulate from coming in contact with the hardened chrome piston rod or getting into the valve packs. We reinforce the system with a multi-layered pressure resistant sealing package, mono block guide system and a low friction piston band which works inside the pressure resistant internal damper housing.
