The ST XA coilover kit allows you to adjust the look of your vehicle with the stepless lowering. We manufacture the adjustable spring perch from a resistant and friction-optimized polyamide composite material with stainless steel insert. Thanks to the composite material, in contrast to the anodized aluminium spring perches, possible oxidation is prevented. So you can permanently use the height adjustment of your ST XA coilovers. With our in 16 clicks adjustable rebound damping, you can further adapt the perfectly to your car pre-set damper setup to your driving profile with just a few manual steps. The adjustable rebound damping gives you the possibility to adapt the ST coilover kit either more comfortable or sportier.

The galvanized coilover struts are, as usual in the standard equipment, made of galvanized steel and our additional sealing ensures an optimized corrosion protection. We protect the inner values of your high-quality ST coilover suspension including its KW dampers with a low-friction and pressure-resistant damper housing, the use of a hard chromed piston rod and a mono block guiding- and sealing package.

Do you want to get more than just a lowering of your car? Then our ST XA coilover kit is just the right suspension for you! Thanks to the adjustable KW dampers, you can always further refine our recommended setting for your vehicle, to set your car even sportier or more comfortable. In any way, your vehicle gets a much better road holding with our ST XA coilover kit and it looks great with the continuously lowering.

Features:

  • Direct Steering Behavior
  • Improved Handling
  • Increased Driving Comfort
  • Composite Spring Perch
  • Two Piece Racing Spring System
  • Dust Protection andamp; Weather Resistant

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.

Daughter ranks it 5/5. I rank them 4/5 due to heel comfort.
Size: 8, Color: Black, Size: 8, Color: Black
My foot is 9.44 inches long which usually places me in a 7.5. For this chart, it suggested the size 8. It's a perfect fit. The back zipper is easy enough to use. You don't even really need to undo the top strap once you have it adjusted to your preferred spot. My foot is narrow to normal around the heel and I'm wider in the toe box. These heels accommodate that well. I have plenty of room around my toes. The toe strap isn't smashing down either. The shoes seems well-made. The straps do not have a threads hanging. There's no sloppy glue drips around the bed. The bottom is strong and the heel is solid. I'm not a huge fan of thicker/chunky heel looks usually. I like the skinner heel styles mostly but ... there's a big positive to the chunky heels. They're very easy to walk in. Great heels for non-formal occasions. The bottom is not slippery. The cushioning around the toes in very nice. My only complaint is that the cushioning by the heel feels inadequate- especially at this price. It feels like you're walking on a block of wood. For that reason, I gave them to my middle schooler. She's thrilled. She pranced around the house in them testing them out for herself. She adjusted well to walking in them and she finds them comfy.

Size: 9, Color: Smoke Grey
These shoes are some of the comfiest heels I've ever worn! The heel actually has a nice height to it, but it's at a gentle slope that feels very comfortable. The heel itself is thicker, which makes it easier to walk, and I love the ankle strap for added security. The shoe's construction is solid, the materials are durable, and the zipper at the back of the ankle moves smoothly. I got the smoke grey color, which I think is really more of a lighter skin tone color, so I don't really agree with the name, but the color is accurately represented by the photos on the product page. This is a great neutral shoe that will pair with many different outfits. It's high quality and versatile, so I think it's well worth the cost. I love my new shoes!

Well made, true to size, comfortable, and attractive looking!
Size: 12, Color: Black
Wife was wanting a new pair of heels for a work party she has coming up and I happened to see these and thought they strongly resembled what she was looking for so I got them as a surprise for her. They arrived a few days ago and she tried them on that night and wore them around the house and to work a couple times to see how she likes them. So far, she is extremely pleased with them! She said they fit perfect and she's had no issues with comfort wearing them all day for work. She really likes the wider heel as it gives her more stability. Her favorite thing so far though has been all the compliments/comments she's getting from the other ladies in her office about them.

Lucky Brand nailed it with these sandals. The craftsmanship of the leather is top notch. I love the look of the crossover straps, they add a chic touch to any outfit. The fit is fantastic, I ordered my usual size 9 and found them to be perfectly true to size.
