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 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 more track stability and 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 aluminum 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 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 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
  • Aluminum adjustable uniball top mounts (when possible)
  • Scaled camber adjustment (optionally also caster)
  • Externally adjustable damping

ADVANTAGES OF A ST COILOVER SPRING STRUT:

  • ST Suspensions - Spring Strut Construction
  • Excellent all around performance, provides a balance between performance and comfort for everyday use
  • High-quality components for long durability
  • Use of twin-tube technology, independent reactions from damping inputs minimized chassis vibrations and increase driving dynamics
  • Coilovers come with all necessary components, vehicle-specific certificate and insallation instructions

 

Functional principle of twin tube shock absorbers
With a Twin-Tube shock absorber, the piston works inside of an inner Tube. The space between the inner tube and the casing is used as an equalization chamber. Changes in volume due position of the piston rod change the oil level in the equalization chamber between the outer casing and inner Tube.

Compression phase:
When the car swings downwards in the direction to the road, the piston rod is moved downwards.The oil displaced by the piston rod is pressed into the equalization chamber between the Tubes via specially designed orifices in the compression valve at the lower end of the inner Tube. The resistance that is created through this valve creates the actual compression forces. Oil underneath the piston also flows upwards through the piston check valve with low resistance which also influences the damper characteristics.

Rebound phase:
When the car swings upwards, away from the road, the shock absorber is extended. The piston rod is extending outward from the housing. The rebound phase valve at the lower Tube resists the oil that flows downwards through the holes in the space above the Tube. Therefore the upward motion is slowed down. When the piston rod is pulled out of the case, its volume is balanced out by the oil that flows from the equalization chamber back into the inner tube through the compression check valve.



Functional principle of mono tube shock absorbers
With a one-piston shock absorber, the piston works directly in the damping case. Both, traction and also compression phase valve are integrated into the piston at the end of the piston rod. Depending on the velocity with which the shock absorber is compressed or extended, the forces rise. A characteristic is the separating piston that separates the oil from the gas space which is under strong pressure. The gas space balances the oil expansion with temperature differences and volume changes while the piston rod retracts. The separating piston thereby moves upwards and downwards. The gas pressure of 25-30 bar in the separating space is necessary in order to support the damping forces in direction of the pressure direction.

Compression phase:
When the car swings downwards in the direction to the road, the piston rod is moved downwards. The compression phase valve on the top of the valve resists the oil that streams upwards through holes. Therefore, the downward movement is slowed down. The separating piston is thereby lowered by the same degree as the piston retreats downwards. The gas pressure underneath the separating piston thereby prevents the oils from foaming above the piston.

Rebound phase:
When the car swings upwards, away from the road, the shock absorber is extended. Thereby, the piston rod is moving out of the damping case. The rebound phase valve at the lower piston resists the oil that flows downwards through the holes in the space above the piston. Therefore the upward motion is slowed down. The separating piston is thereby lifted upwards by the same degree as the piston extends.

The white shirt, blue vest or jacket, and coordinating accessories create a clean, formal look that works beautifully for weddings, photos, and other warm‑weather events. The fabric feels lightweight and breathable, which is exactly what you want in a summer suit. The double‑breasted jacket adds a stylish, elevated touch without feeling too heavy, and the pants have a comfortable fit that gives kids room to move. The included bow tie and necktie make it easy to switch between a more traditional or modern look, and the overall sizing appears accurate for a formal set. As a full five‑piece outfit, this is a convenient, ready‑to‑wear option for parents who want something sharp and cohesive. It photographs well, feels comfortable for kids, and offers great value for a complete formal ensemble. A solid pick for ring bearers, family photos, or any special occasion.

Adorable, Complete Set—Great for Special Occasions
Color: Beige, Size: 12, Color: Beige, Size: 12
This suit set is such a great find! It comes with everything you need—jacket, pants, shirt, tie, and bow tie—which makes getting a dressed-up look so easy. It's excellent quality for a suit in this price range. The linen fabric gives it a nice, lightweight feel and a polished look that works well for both formal and semi-casual events. My son looked adorable in it, and it was perfect for the spring wedding we attended. What I love: Complete 5-piece set—no need to buy extras Lightweight and comfortable material Classic, stylish look with nice details (lapel, pockets, etc.) Adjustable waistband is super helpful for fit Versatile for weddings, holidays, and other events Fit was true to size based on the chart, but I agree with the recommendation—if your child is between sizes or growing quickly, sizing up is a good idea. I sized up with the hopes that he can wear it again for another event because it looks fantastic! Overall, a really cute and practical suit set that looks great without being uncomfortable. Perfect for any special event

Boys’ 5‑Piece Linen Suit Set
Color: Beige, Size: 16, Color: Beige, Size: 16
I ordered this 5‑piece linen suit in size 16 in the beige color. The set includes the jacket, pants, dress shirt, bow tie, and a slip‑on tie. The outer fabric is a blend of 70% polyester, 25% linen, and 5% spandex, and the lining is 100% polyester. The material is lightweight, which works well for warm‑weather events, but the pants are noticeably thinner than the jacket. The jacket feels sturdier because of the full lining. The jacket has a peak lapel, flap pockets, and cuff buttons, and the stitching and seams are tight and even. I did notice a few loose threads, but the fabric itself was smooth with no tears or flaws. The pants have an adjustable waistband, which is helpful, but the length was too long and will need to be tailored. The overall cut of the suit seems designed for children on the thinner side. The shirt included in my set was a pleated style rather than a plain dress shirt. It wasn’t the style shown in the product photos, and I would have preferred a standard shirt that could be worn for various occasions rather than a very formal shirt. The tie is a pre‑tied slip‑on style with an elastic band. I would have preferred a traditional tie instead. The suit arrived in good condition with no damage, and the color was even throughout all pieces. The price is on the higher end for similar 5‑piece sets. I rated it 4 stars because the jacket is well made and the set includes all the expected pieces, but the thin pants, unexpected pleated shirt, and slip‑on tie kept it from being perfect.

Got this suit set for my son and absolutely love it. It comes with everything he needs to look sharp, and I really appreciate that it includes both a tie and a bow tie so we can switch up the style depending on the occasion. The quality is impressive for the price — the fabric feels light and comfortable, and the whole outfit has a polished look without being stiff or uncomfortable. The fit was spot on, and the adjustable waistband is a huge help for getting it just right. My son looked great in it, and it’s definitely something he can wear for more than one event. The little details on the jacket and pants give it a classic, dressed‑up feel that works for weddings, holidays, or any special moment. Overall, it’s a stylish, practical set that makes getting him ready so much easier. Really happy with this purchase.
