For those who demand the absolute best performance comes the ST XTA coilover. The full driving behaviour of your car can be adjusted using KW damper technology along with an adjustable aluminium uniball 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 bodyroll. If the rebound force is decreased, the car will feel more comfortable when on the move. For increased performance, the ST XTA features an aluminium adjustable topmount 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! NOTE: The lowering of each vehicle differs greatly with ST XTA coilovers due to the type of construction. For example, older vehicles such as the Honda Civic (EJ9) can be lowered between 40-75mm with ST XTA coilovers, while newer models such as the Audi S3 (8P) can be lowered between 10-40mm due to being much lower from the factory.

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 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, spring system and bumpers with dust protection
- Aluminium adjustable uniball top mounts (when possible)
- Scaled camber adjustment, when possible
- Externally adjustable damping

Good but check screws for looseness, mine had an arm fall off.
Color: Black
A screw fell out and the arm fell off soon after beginning to use them. Aside from that they are fine. Repaired by buying a $10 eyeglass repair kit.

Better than expected!
I initially got these for the look, but they turned out to be pretty solid sunglasses in thr end. They're comfortable, functional and durable, and I'm always getting compliments on them

very large, but otherwise perfect
Color: Black
Was looking for glacier sunglasses, at a reasonable price, and polarized. I found these and bought 4 pairs, one for each family member, for an upcoming trip. Glass look great! They are lightweight, polarized and have the side shields we needed. But, they are huge! All four must be returned. They don't fit any of us. It's a shame...they are perfect, besides the size. But glacier glasses must fit snugly to the face and these are far, far from our skin.

The Best Sunglasses
Color: Black
I was hesitant to purchase these at first. I'm so glad I did, though. They are light-weight, comfortable, and super stylish. I work in the desert, so the side guards are very helpful in keeping the sand and dust out (not entirely, but they help). I will absolutely purchase again.
