The ST X Coilover suspension was developed for the everyday driver who needs to hug the curves yet retain road comfort. Simple, uncomplicated road performance for those who just want to get in and drive. Add in our wide range of height adjustability; the ST X Coilover will look as perfect as it feels. ST XCoilover kits deliver precise adjustment to your ride height and look of your car. We manufacture an 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. 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. At ST suspensions we do not accept compromises. As a matter of principle we rely on world class engineering delivered from KW for all our dampers. Why? To simply improve your driving experience! All ST X Coilover kits are application specific for your car and perfectly adapted for everyday life.

  • Elastomer Bump stop with integrated dust protection system prevents water and dirt particles reaching the piston rod and seals. The highly resilient bump stops act as dynamic load limiters while maintaining ride quality and durability.
  • Composite spring perch made from wear-resistant, friction-optimized polyamide composite with an embedded stainless-steel insert. The polyamide composite prevents oxidation while the stainless-steel insert maximizes strength.
  • ST X coilovers are the ideal mix of sporty yet simple. The dampers and spring rate come tuned by our vehicle dynamics engineering in Germany to perfectly match each vehicle specific application.
  • ST coilovers are built by hand by the experts at KW in Fichtenberg, Germany. Each damper is tested on a shock dyno to verify it's making the proper forces before being put into the ST box.
  • Seamless Ride Height Adjustment - ST's composite spring perch and unique trapezoidal thread pitch make ride height adjustability a breeze so you can dial in your preferred look.
  • Galvanized steel housing for improved resistance to corrosion.
  • 5 Year Limited Warranty - Unlimited Mileage
  • Made in Germany

Good quality fits 2025 Civic Hybrid
The filters are good quality. I did not find any instructions, but then again, the tube is full of them. Compaitble with 2025 Civic Hybrid. The engine filter have a bit of a chemical smell, but the air cabin filter does not. The cabin filter has an interesting yellow color.

Quality filters for a decent price
The engine filter is model # JMAJ20. I am not sure of the cabin filter model #. I have a 2026 Honda CRV Hybrid 2.0L Sport Touring. These should fit as almost everything matches between the 2025 and 2026. I have not yet needed to swap the filters in the new vehicle. These filters will be stored for future replacement. The filters appear to be well made. This is a decent price fortwo filters. The engine filter's gasket is a little wavy but it should be ok to form fit once inserted into the car. The engine filter is in a retail box without a plastic wrapper but the cabin filter is just a plain cardboard box inside a plastic wrapper. This might be challenging to remember what is in the box later once the filter needs to be replaced unless I write the information onto the box. I am unsure if the lack of a wrapper for the engine filter will affect the filter while stored. I did not notice a smell to these but I am not sensitive to smell. I would get these again.
