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

Product doesn't work as advertised
This product does not provide enough wipes to remove more than the minimum amount of oxidation. The headlights were starting to yellow, so the oxidation was not severe. We followed the directions on the box to the letter and after using the wipes as directed were left with a sticky residue (which was left-over oxidation that the drying wipes could not remove). I am forced to purchase another box of the product in order to complete the job. I can't drive my car around with the tape protecting the body of the car on it, plus this is Florida so there would be bugs stuck in the tape and the sticky residue. A terrible product. Plus when I called them they said they would send me an email so I can tell them what the problem is and they would give it to their "research" staff to handle. I'm doing that and perhaps they will reimburse me for the second box I will have to get overnighted in order to finish the job.

Armor All Car Headlight Cleaner Wipes – Quick & Easy Clarity
The Armor All Car Headlight Cleaner Wipes are a convenient and effective solution for restoring foggy, yellowed, or hazy headlights without the need for complicated kits. These pre-moistened wipes make it super easy to wipe away oxidation and dirt, improving visibility and enhancing the car’s overall appearance. ✅ Pros: Quick & Easy to Use: No need for additional tools or sanding. Restores Clarity: Helps reduce haze and oxidation buildup. Convenient Packaging: Portable and easy to store in the car. No Harsh Chemicals or Strong Odors. ⚠️ Cons: May Require Multiple Uses for Heavily Oxidized Headlights. Not a Permanent Fix: Works best for maintenance but may not fully restore very cloudy headlights. Can Leave a Slight Residue: Needs buffing for the best shine. Final Verdict: For a quick fix and easy maintenance, the Armor All Headlight Cleaner Wipes are a great go-to option. They work well for light oxidation and keeping headlights clear, but for severely foggy lights, a full restoration kit may be needed. Great for touch-ups and convenience

Foggy foggy to crystal clear in less than an hour!!! True story!
Pleasantly surprised at a)how easy this kit was to use, b) the results of the kit and I highly recommend this kit. Took my headlights from completely foggy to crystal clear as if they were brand new. Only took about 30 minutes with a little elbow grease. Great product at a great price!

If you buy it, buy 6 or 7,8 boxes
This is a great product! If you buy 6 to 7 kits! Making it very expensive!!! Once you get started, you can’t stop without buying more kits. It gets worse and worse using any other product. It last a good 8 to 12 month, if you use 7, 8, or 9 kits. It will work the crap out of you, wiping and wiping, scrubbing! Don’t even get started with it, they give you enough of the good stuff to work on a 2 year old car, showing zero signs of oxidation. I’m an Armor All fan! Armor All has the best interior cleaner, a good protectant, & many other good products.. but this product has cost me money and a lot of time. Not happy Armor All.

wow, ahead of the rest, easy to use
Style: Headlight Restore & Repel Kit
wow, i have used a lot of products for my cloudy headlight lens. this was the easiest and the best so far. on a dry clean headlight, open the foil envelope and get the wipe out, wipe the cloudy headlight and it really gets the job done, a yellow stain builds up on the wipe. one wipe for each headlight. wipe dry with microfiber, then spray the sealant and let it sit, just wipe any excess run off on the car body. poof, done! looks good. says it can last up to 18 months. not sure about that, but i will take what i have now. go nu finish, another solid product.
