Need to get low? ST coilovers feature a continuous thread construction for height adjustment from moderate to eXtreme! Each coilover is manufactured by KW automotive's expertise and capabilities ensures maximum quality and fantastic driving dynamics.

Once installed, the ST X coilover can easily be adjusted using a polyamide ring on the galvanized, multiple-sealed strut. Adjustment is different for each car, but typically you can expect between 35 and 65mm of lowering on both the front and rear axles. For lowered cars as standard (such as the BMW E9x 3-series) the ST X coilover features a range of 30 to 60mm (front axle) and 25-55mm (rear axle).

Improved driving dynamics and handling- Designed in conjunction with KW Germany, ST X coilovers deliver a sporty handling by reducing the car's bodyroll during compression as well as improving agility when driving fast. The high quality production of each ST X coilover includes a low-friction and pressure resistant housing alongside a chrome-plated piston rod for maximum longevity. A mono block guide and ST seal package ensures the twin-tube dampers remain free of dirt particles in all weather conditions.


Lowering with Style: the ST X coilovers

  • Individual lowering within the TUV-tested adjustment range
  • Front and rear axle thread adjustment (when possible)
  • Galvanized coilover struts with additional coating for optimized corrosion protection
  • Complete solution with adjustable spring plate, race spring system and bumpers with dust protection
  • Powerful twin-tube dampers with high-quality components for maximum longevity

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.

Hawaiian Tropics highly recommended for sensitive skin.
Scent: Island Coconut, Size: 0.35 Fl Oz (Pack of 1)
Love this product. This is my first summer using it. I was not disappointed. I have super sensitive skin, and can’t use most products. One thing I did notice was a few times I would get a small pimple or blackhead along the lip line. The dermatologist said it was clogged pores, but no reason not to continue using it. I have tried a few other brands and had more breakouts/ blackheads. So I keep going back to Hawaiian Tropics.

Reliable protection that stays put during workouts!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I’ve tried many expensive name-brand sunscreens, but this Amazon Basics version performs just as well, if not better. It’s become my go-to for morning runs and trips to the beach because it actually stays on even when I’m sweating. Why I gave it 5 stars: Non-Greasy Formula: Unlike other sport sunscreens, this one absorbs quickly and doesn't leave that heavy, sticky film on my skin. Actually Water Resistant: I’ve used it for laps in the pool and long hikes; as long as I reapply as directed, I haven't had a single sunburn. No "Sting": One of the best things is that it doesn't run into my eyes and sting when I start to sweat—a huge plus for runners. Great Value: You get a generous 8-ounce bottle for a fraction of the price of "premium" brands. The fact that it’s formulated without Oxybenzone is an added bonus for peace of mind. If you’re looking for effective, no-frills sun protection for an active lifestyle, you can't beat this. It’s a staple in my gym bag now!

Great value and very practical
Style: SPF 50, Size: 8 Fl Oz (Pack of 6)
This sunscreen is a great value for the price. The SPF 50 protection works well and the lotion applies smoothly without feeling too greasy. It absorbs nicely and provides good coverage for outdoor activities. I especially like using these bottles to refill the sunscreen dispensers at my Airbnb for guests. It’s convenient, reliable, and affordable when you need multiple bottles available. Overall, it’s a solid everyday sunscreen and a very practical option if you need good protection at a reasonable price.

good price for good product. applies well, shake and store upright
Style: SPF 50, Size: 8 Fl Oz (Pack of 1), Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I believe it is equal to the name brands It is 50 SPF Sun Protection Factor so it offers strong UV A and UV B protection which are the 2 ranges of sun rays that do the skin damage and burning. It is an easily absorbed lotion that when rubbed goes into the skin and is not visible. It is thick and goes on with a non shiny, non greasy, solid thick feeling which is what we need for it to stay on as long as possible. It feels good after being rubbed in in that it feels dry and not overly greasy or with no shine and sheen. It is a good product and offers burn protection to me in some clear-sky strong sun uses. Reapply after entering the pool water or swimming laps and after an hour (all sunscreen labels say reapply after 80 minutes which I believe is per recommendations of the federal FDA or some medical studies). I reapply often and I still get tanned but I do not want to burn.
