    For those who demand the absolute best performance comes the ST XTA coilover. The full driving behaviour of your car can be adjusted using KW damper technology along with an adjustable aluminium uniball top mount for fine-tuning of the camber and caster!

    ST XTA coilovers feature KW damping technology which allows the suspension to be made either stiffer or softer depending on the driving conditions. This damping adjustment is made on the upper end of the chromed piston rod allowing the setup to be changed almost instantly. If the rebound force is increased, the car will drive with even more track stability and further reduced bodyroll. If the rebound force is decreased, the car will feel more comfortable when on the move. For increased performance, the ST XTA features an aluminium adjustable topmount allowing the camber and caster to be adjusted depending on your driving needs or vehicle setup.

    Like all ST coilovers the lowering adjustment is made via a continuous thread on the galvanized strut. This even allows the lowering to be made even when the kit is installed by turning the spring plate higher or lower!

    NOTE: The lowering of each vehicle differs greatly with ST XTA coilovers due to the type of construction. For example, older vehicles such as the Honda Civic (EJ9) can be lowered between 40-75mm with ST XTA coilovers, while newer models such as the Audi S3 (8P) can be lowered between 10-40mm due to being much lower from the factory.

    The high-quality ST XTA coilover is based on the twin-tube damping principle of low friction combined with pressure-resistant damper housings. Manufactured directly at KW, a mono block guide and seal package reduces the friction of the damper as well as protecting it against corrosion and dirt. Each galvanized strut is sealed multiple times to ensure maximum longevity in ALL weather conditions.

    - Latest damping technology for maximum longevity
    - Reduced system friction for effective damping adjustment
    - Individual lowering within the tested adjustment range
    - Front and rear axle (when possible) with thread adjustment
    - Galvanized coilover struts with additional coating for an optimized corrosion protection
    - Complete solution with adjustable spring plate, race spring system and bumpers with dust protection
    - Aluminium adjustable uniball top mounts (when possible)
    -vScaled camber adjustment (optionally also caster)
    - Externally adjustable damping

    ST Suspensions - Make it yours!

    From now on you can customize your ST suspensions coilover kit and adapt it to your individual needs. For example you can select your favorite spring colour out of many options or add an additional marking on the springs. Create your individual spring with an additional spring marking of up to 25 letters which will be printed on a separate winding below the tüv marking. (A-Z and whitespaces is allowed).

  • Brand
  • ST Suspensions

    ST Suspensions was founded in the early 80s in Southern California. Back then, the brand was called Suspension Techniques and developed many new and innovative products that the market lacked. By using quality materials, modern techniques and fast production, they created a really good value for the customer. At this time, they focused mainly on the Sportcompact market and the brand quickly grew strongly throughout the USA.

    In 2005, German KW Suspensions bought Suspension Techniques and their then owner Belltech. KW, known worldwide for their stainless coilover kits, then started KW Automotive North America Inc, which became their American division. At the same time, they changed the name of Suspension Techniques to ST Suspensions.
    At the same time as merging these, they brought in the technology from KW's dampers and took ST to a whole new level. Here they started manufacturing ST's new coilover program which is based on KW's Inox series, but in order to maintain an aggressive price image, a galvanized and coated damper body is used instead of a stainless one. This is to get a slightly lower production cost than the market leading KW damper.

    KW and ST together are one of the most well-respected coilover manufacturers, which is based on the enormous time spent on R&D for each kit. Here, the springs and shims of the coilovers are tested in a 7-point rig. Something that can almost be described as a dyno bench for shock absorbers. The coilovers are therefore very well tuned for each application, which is most clearly seen in all satisfied customers worldwide!

    ST Suspensions has several different series to suit the type of driving the product is to be used for! Everything from the slightly simpler ST X to the track coilover XTA Plus 3!
