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

Issues with mounting the shelves, big time
Color: Brown, Size: 55.1"W x 10.3"D x 1.8"H, Set of 2
I bought the 55 inches floating shelves. I have an area above my linen cabinet that I wanted to utilize for storage and books in my hall. I did my measuring, figured out spacing. Marked everything off to do 3 total shelves (bought two boxes). A couple of spots screwed into a stud, and the others I had to install the plastic mount things. I had used those before so I just did the predrill then tapped them in, finished off by screwing the mount flush with the wall. I grabbed the first bracket and decide to start with a screw that had one of the inset mount things (sorry the correct term is escaping me). It never once occurred to me to check that the plastic mount and screw would not work. We’ll surprise! I tried and tried to get the screw to screw thru the mount, the mount is the rigid plastic thoe that is supposed to split when the screw goes through. Well something wasn’t engineered properly on the mounts cuz they would not thread a screw. They would not split. I even went into my garage and tried different screws I had to see if maybe it was just too big…or something. Then I started just prying it apart and could not get it to split like it’s supposed to, the tip piece broke off before the piece split. I have never had this situation before. I now have a bunch of these, that leave huge holes in my wall, where I measured out for a shelf to go. I’m not a huge DIYer so now I’m trying to figure out if I can salvage this situation but I’m afraid that if I get different mounts they will be too small for the already created holes, or they will fit the hole but because it’s screwing into dry wall, the drywall already has threads from the other mount, will it strip if the threads aren’t 100% the same. Oooooor am I going to have to patch up and paint that wall, then buy new mounts and attempt to try again….which I will now have to set the shelves at a different height so I don’t screw into the same holes I patched since I don’t trust them…..ugh. I practically want to cry. lol. So if I could give this negative stars I would! I feel stupid due to these having such great reviews by others. Comments of how easy they were to install. I will also mention that a few others mentioned the metal bracket that is mounted to the wall then the shelf slide onto is very flimsy. I could bend it side to side with my hands. The only reason I decided it would be ok is that there are a total of 8 screws in the mount, figured it would be stable enough.

Decent Quality. Look Great
Color: Brown, Size: 35.7"W x 10.3"D x 1.8"H, Set of 2
These are easy to install and the shelf has a good quality look. The only thing lacking is the quality of the bracket. The arms are thin metal and I feel like it won’t hold much weight.

Great quality and easy install
Color: White, Size: 55.1"W x 10.3"D x 1.8"H, Set of 1
Great quality. Very easy install. Mounted mine above my fireplace to create a mantel. Looks like it was there from the day the apartment was built. So far it has held a good bit of weight with heavy ceramic decor and one very fat cat jumping up on it lol.
