For those who demand the absolute best performance comes the ST XTA coilover. The full driving behavior of your car can be adjusted using KW damper technology along with an adjustable aluminum uni-ball top mount for fine-tuning of the camber and caster! Performance driving in mind ST XTA coilovers feature KW damping technology which allows the suspension to be made either stiffer or softer depending on the driving conditions. This damping adjustment is made on the upper end of the chromed piston rod allowing the setup to be changed almost instantly. If the rebound force is increased, the car will drive with even more track stability and further reduced body-roll. If the rebound force is decreased, the car will feel more comfortable when on the move. For increased performance, the ST XTA features an aluminum adjustable top-mount allowing the camber and caster to be adjusted depending on your driving needs or vehicle setup. Easy lowering adjustment Like all ST coilovers the lowering adjustment is made via a continuous thread on the galvanized strut. This even allows the lowering to be made even when the kit is installed by turning the spring plate higher or lower!

KW Engineering: Exclusive for ST suspension The high-quality ST XTA coilover is based on the twin-tube damping principle of low friction combined with pressure-resistant damper housings. Manufactured directly at KW, a mono block guide and seal package reduces the friction of the damper as well as protecting it against corrosion and dirt. Each galvanized strut is sealed multiple times to ensure maximum longevity in ALL weather conditions.

- Latest damping technology for maximum longevity
- Reduced system friction for effective damping adjustment
- Individual lowering within the TUV -tested adjustment range
- Front and rear axle (when possible) with thread adjustment
- Galvanized coilover struts with additional coating for an optimized corrosion protection
- Complete solution with adjustable spring plate, race spring system and bumpers with dust protection
- Aluminium adjustable uni-ball top mounts (when possible)
- Scaled camber adjustment
- Externally adjustable damping

Suspension Techniques (ST) Coilovers are made by KW, the leading brand worldwide for height adjustable coilover systems. The ST coilover is identical in valving and technology as that of the KW Variant 1, only difference is the galvanized steel casing, opposed to the stainless steel casing of its "big brother" KW.

Almost perfect
Style: Screen+Charger
Solid mount. I’ve tried other ones but they don’t sit as nicely as this one. It also has a lot of adjustments to allow for using it any way you need it to so it is very versatile. The magnet strength is really good and holds my phone really well. Sometimes it feels too strong which I guess is a good thing. The charging works well but I wish the cable was a little longer

Super easy to set up
Style: Screen+Charger, Style: Screen+Charger
I couldn’t be happier with this car phone mount—it’s easily one of the best accessories I’ve added to my vehicle. The build quality feels solid and durable, with a strong grip that keeps my phone securely in place even on bumpy roads. Installation was quick and hassle-free, and it holds firmly without slipping or needing constant readjustment. What really stands out is how easy it is to use one-handed. I can mount or remove my phone in seconds, which makes a big difference while driving. The adjustable viewing angles are perfect for navigation, and it doesn’t block my view of the road at all.

Poor socket design.
Style: Holder+Dash+Vent+Windshield
Overall this is a pretty decent phone mount. I have used it with both the windshield and vent mounts. The only problem I have is the design of the ball swivel. The socket contains a rubber piece to help increase the grip, but over time heat from the sun or the air vent makes the ball glue itself to this rubber piece. When you try to make an adjustment, the ball will not move in the socket and ends up breaking the socket. This is happened to me twice.

Great Phone Holder
Style: Holder+Dash+Vent+Windshield
I bought the version with the suction cup mount and I’m very happy with it. It holds my phone securely in place and doesn’t move around while driving. It’s also very easy to place the phone in the holder and remove it when needed. The suction cup sticks well to the dashboard, and you can position it so the phone stays in a safe, easy-to-see spot while driving. Overall, a great and reliable phone mount. Highly recommend!
