Looking for maximum performance for your car? Our adjustable ST XTA Coilover kits are the upgrade you need. All ST XTA systems are delivered with a linear race springs system, adjustable dampers, and aluminum unibal camber adjustable top mounts. ST XTA Coilover kits deliver precise adjustment to your ride height so you control the look of your car. We manufacture the 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 while the stainless steel insert provides strength and confidence! ST XTA Coilovers come preset to our factory recommended damper settings, the same configuration we test them at on our KW shock dynos before they go into your box. The 16 distinct clicks of adjustable rebound damping allow you to refine the driving dynamics with a simple turn of the adjustment knob. Each kit includes a detailed damper setup manual making it easy to reset to our recommended setting at any time. Whether your preference is comfort, performance, or something in between; ST XTA puts the finer details of the driving dynamics in your hands. The top mounts included with our ST XTA Coilover kits allow you to adjust the camber at the front axle to dial in aggressive wheel and tire fitment. They also allow you to maximize the tire's contact patch for driving in fast corners and any other driving scenario that demands maximum grip. 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.

  • 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 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.
  • Linear race spring system provides a consistent response while driving and makes it easy to swap rates to further personalize your setup.
  • Aluminum unibal top mounts improve steering response and feedback while allowing you to dial in your camber when applicable.
  • ST XTA coilovers feature adjustable rebound damping which puts you in control of how comfortable or sporty your car feels.
  • Galvanized steel housing for improved resistance to corrosion.
  • 5 Year Limited Warranty - Unlimited Mileage
  • Made in Germany

Nice but short
Size: X-Large, Color: Lavender
Yes, I purchased this shirt for my husband to wear on Mother’s Day. He looked so handsome and the color complimented his skin tone beautifully. The only con that my husband expressed was that the shirt was short but was comfortable and the fabric felt good on his skin. He is 6’3” and usually wears an XLT. Coofandy, Please make these shirts for taller, longer torso men!

Expensive Look Without The Expense!
Size: Medium, Color: Black, Size: Medium, Color: Black
Sizing: If you’re a true large like me and close to but less than fifteen pounds overweight, normal length and with a 44” chest, buy a medium and use the shirt to inspire you to lose the beer belly. If you have similar dimensions but are overweight by up to thirty pounds, get the large. Materials: The mediums are manufactured to 70% synthetic, 30% linen—which is a great mix, as is doesn’t have to be ironed after it’s washed and hung to dry, nor does it have to be ironed every time you get up from a chair. I’ve had many 100% linen shirts and sure, they look great after you spend thirty minutes ironing them, just to look like a crumpled up newspaper after you get out of your car. My experience with linen shirts is what brought me here. Unboxing the shirt: I threw it on an ironing board the moment I unbagged it. I tried the Synthetic setting on the iron—it wasn’t enough. I then tried the Wool setting and set the steam setting to constant medium to high. It worked great. I didn’t have to press down at all, just lightly glided the iron across wrinkled areas of the shirt. Within five minutes, the shirt looked like a hundred-dollar shirt. The material is light, yet feels heavy to the touch and breathes very well in the heat. The hidden buttons give a clean, modern look that allows the shirt to be worn with anything from shorts and sandals to dress slacks and shoes in a club. I like to wear these shirts, untucked with a pair of jeans and western boots. This shirt is very comfortable, fits nice and is extremely versatile.

Great for the price
Size: Medium, Color: Grey
Nice and light material. Looks good. Suitable for hot temperatures and casual attire. The only thing I've noticed so far that isn't so great, is that the buttons are rather cheap and the middle part broke out on a few of them.

Impressive solution for the price
Configuration: 3-pack, Style: without eero Plus
I'm a network engineer snob who won't hesitate a single second to give most of the home router and wifi junk sold today a terrible review when it's warranted. After having two router/wifi solutions made by that company that starts with Net and ends with Gear fail on me in less than 6 months, I was about ready to spend a few grand on a Ubiquiti solution and wire up my home for access points and cameras. Then a colleague and friend of mine suggested this eero mesh system as a lower cost/effort option. I'm not a fan of plug and play stuff and was skeptical but figured I could return it if not happy. I have to say I'm pretty impressed. The set up was almost too easy. Just download the eero app to your phone, plug a device in and connect the 2.5g port to your router and the app will walk you through it all. Most importantly, it worked really well when solutions like this from other vendors don't forcing you to connect a cable and manually set up. At first I didn't like that there isn't any ability to give the 2.4ghz and 5ghz networks different SSIDs (I had my previous router set up this way and changing this would have meant climbing up a ladder and reconfiguring several Ring cameras) but eero let's you change the name of the Guest Network to anything you want so this was an easy work around. As others have mentioned download the Wifiman app and shortcut and start scanning your house after you install the main router/wifi device. When you find spots that the signal drops below GOOD quality (-70dbm) drop another unit in between the first and where the signal dropped to poor quality. I bought the 3 pack thinking I'd need it to cover a 6,000 sq ft home. However one device was provided good coverage for most of my house and two provided either excellent or good signal strength everywhere inside and even outside on my patio and driveway. I only have one device on the first and second floors and both floors as well as the basement are all receiving good/excellent signal quality. I could have definitely saved $100 and gone with a two pack but I'm ok with having an extra device as a back up or if someone else in the family needs it (keep in mind any of these devices can act as a standalone router/wifi solution) or even to temporarily extend WiFi farther out into my yard in fair weather for outdoor gatherings etc.. Overall I'm impressed. The dashboard and tools/analytics included with the app are more than adequate for home users. You can even set up alerts for new devices connecting to your network. The GUI is modern and responsive and not like some of the traditional router vendors who still support an antiquated web login that takes forever to connect, lags between function and times out frequently. Time will tell if this is reliable but as mentioned a friend and colleague who owns his own network solution business told me he installs these in homes where the cost and wiring of a Ubiquiti or similar solution is prohibitive and he's never had an issue with their performance and reliability.

Configuration: 3-pack, Style: without eero Plus
Not sure why this doesn’t have 5 stars from everyone! Got the three device set up and man this couldn’t have been easier to set up. This system is bomb, like I’m not sure how much easier of a setup people even want. Everything was basically plug-and-play, and the app walks you through it so smoothly it almost feels too easy. Performance-wise, it’s been amazing. The coverage is solid throughout the whole house, and the speeds are not just fast—they’re consistent everywhere on Wi-Fi, not just when you’re hardwired. I haven’t had any random drops or dead zones like I used to deal with. Compared to the Cox gateway, it’s not even close. They charge $15 a month to rent that thing and it doesn’t hold a candle to this setup—honestly kind of ridiculous. And the quality? Top tier. It honestly feels like an Apple product. From the packaging to the devices themselves, even the cords and the app—everything just feels super polished and premium. I’m actually glad Amazon acquired eero because you can see that level of refinement in the whole experience. My only complaint is the price tag. $400 is definitely not cheap. But when you break it down, Cox charges $15 a month to rent their gateway—that’s $180 a year. In just about two years, this system basically pays for itself, and you’re getting way better performance the whole time. Overall, 110% happy with this purchase.
