Individually Height Adjustable

ST XTA coilover kits deliver precise adjustment to your ride height so you control the 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 XTA 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 16 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, performance, or something in between; ST XTA 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
  • Improved handling
  • Pitch and roll movements
    of the 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

Precise handling due to adjustable Unibal top mounts.

The top mounts included with our ST XTA coilover kits allow you to adjust the camber at the front axle to dial in aggressive wheel and tire fitment. They also allow you to maximize the tire's contact patch for driving in fast corners and any other driving scenario that demands maximum grip.

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.
