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

Best Construction Kids book
Format: Hardcover
My nephew can look at this book for hours. It is such a cool book even for adults. It is a more delicate child’s book as their are lots of demonstrations and paper pieces that move. The house across the street is being torn down and rebuilt and he will sit and point to the book and say this is what they are doing today. I think this book is one of my nephews most prized possessions. It’s a great book that can grown with them for a few years. He is only 3 but this could easily engage a 5 or 6 year old. There is lots of details and the book is really well designed.

Fun, but fragile
Format: Hardcover
This is a cool book, and my 2.5 year old son LOVES it. However it is important to note that it will be destroyed very quickly. There are lots of flaps and moving parts and it is very easy to accidentally rip them off if you try to move one in a way it's not meant for. I ripped more than 1 myself.

Great for training
Format: Hardcover
I order these for new salespeople and managers who have no construction experience. They think it's a joke until they start going through it.

The Darkness Creates Monsters
Format: Paperback
I really like this dark fantasy comic series. A long time ago, the world turned into darkness. The sun did not shine any more, and anybody who was in the dark for too long turned into a monster. Humans still survive. They drive around and live. The monsters are afraid of light. The artwork is really really good. Monsters and humans are drawn with excellent detail. You can actually see what's going on. The fight scenes are easy to understand. Can't wait to read Volume 2.
