Cutting-edge motorsports technology for more performance on the road. With independently adjustable compression and rebound damping the Variant 3 damper setup can be tuned to your own driving preferences or vehicle modifications such as weight, tire characteristics or additional chassis bracing. True performance optimization is only possible with this unique, patented system. For example, the compression damping force can be increased to optimize grip from the tires, or improve cornering behavior and reduce squat without influencing the rebound damping characteristics that are optimally tuned to the spring rate.

The KW Variant 3 "inox-line" coilover kit is the ideal tool for performance-oriented drivers and experienced tuning enthusiasts who place a strong emphasis on the overall performance of their suspension. The Variant 3 features patented TVR-A and TVC-A technology that provides separately adjustable rebound and compression damping. The extensive adjustment range of the independently configurable rebound and compression make it easy to directly influence the steering behavior, directional stability, grip and handling characteristics for confident and repeatable results at the limit of driving dynamics.

With KW Variant 3 coilovers you can achieve maximum lowering within an approved lowering range that ensures a proper functioning suspension with adequate travel after your car is lowered. Even after years of use you can easily adjust the ride height thanks to the dirt resistant trapezoid thread and composite adjustment collar.

KW Variant 3 Coilovers Feature:

  • Customized Suspension Lowering. KW coilover suspensions, KW height adjustable springs, and KW DLC Air Suspensions allow the suspension to be lowered within the vehicle's technical limitations. For example, our Street Comfort products allow for a customized ride height setting with mild suspension lowering from 10 - 50 mm, while the Street Performance products allow the maximum technically possible suspension lowering range from 45 - 85 mm, depending on the vehicle. This means that the suspension can be lowered to suit the personal needs of the user and, depending on the product category, a setting ranging from Comfort to Performance can be chosen.
  • Composite Spring Seat. The KW coilover spring seat, also known as a spring perch, is constructed with a wear-resistant, friction-optimized polyamide composite material encompassing a stainless steel insert. In contrast to the anodized aluminum adjustable spring seats, the polyamide composite material prevents any possible oxidation while the stainless steel insert maximizes strength.
  • Trapezoidal Threads. In combination with the Inox-Line stainless steel coilover struts, this guarantees the long-term functionality of ride height adjustability. In comparison to common coilovers, KW uses a friction-optimized trapezoidal thread which is less sensitive to dirt and requires less force to adjust. Its large cross-section also provides a higher load-bearing capacity.
  • INOX-Line. KW's coilover suspension struts are manufactured from high-quality stainless steel that is rust-proof. In contrast to other solutions, Inox-Line coatings will not wear off while adjusting the suspension making KW coilover struts 100 percent corrosion resistant with an unlimited lifespan. Lowering the suspension using the trapezoidal thread in combination with the polyamide composite spring seat guarantees long term usability. Even after years the ride height adjustability is not affected.
  • Rebound Adjustment. The rebound stage damping is precisely tuned to the respective vehicle at our in-house drive dynamics test facility, delivered in the middle of the range out of the box. Individual customization can be achieved in 16 precise clicks, allowing you to choose between more comfort or more body control. The two-stage patented TVR-A technology allows the oil to flow through an adjustable, conical low-speed valve during slow piston speeds, while during higher piston speeds the main rebound stage valve opens to handle the flow of large volumes of oil. This provides major improvements in ride comfort without influencing the high-speed.
  • External Reservoir. KW Twin-Tube Technology Knows No Limits. The KW reservoirs provide additional oil and cooling capacity for particularly high force systems. The reservoir, which is filled with low gas pressure, can be fitted anywhere and accommodate the adjustable compression valve to provide more working space inside the damper.
  • TVR-A Technology. The two-stage, patented TVR-A (Twin Valve Rebound - Adjustable) technology enables a small volume of oil to flow through an adjustable, conically shaped, low-speed bypass during low damper speeds, while in the case of higher damper speeds, the main rebound stage valve opens allowing a larger volumn of oil to flow. This provides a big improvement in terms of ride comfort without influencing the safety-relevant high-speed range.
  • TCV-A Technology. The patented compression stage valve with TVC-A technology features two separate spring pre-tensioned valves for low and high volume flows. The compression stage which is tuned to the particular vehicle type on our 7-post rig is supplied with a mid-range factory setting. With 12 precise clicks the adjustable compression stage valve can increase or decrease the cross section in the low-speed valve to achieve more or less compression stage damping. At the same time, in the case of sud-den high piston speeds, the spring pre-tensioned needle valve and the spring pre-tensioned main valve open to their maximum cross section, utilizing the blow-off feature to prevent undesired progressive power surges in the high-speed range. This allows for improved bracing of the vehicle body while simultaneously offering more comfort than with con-ventional valve technology in the case of high wheel acccelleration. The compression stage damper setting is always supplied in combination with a separate rebound stage setting, as only one independent 2-way damper setting allows for true performance optimization.
  • KW 7-Post Driving Dynamic Test. Used regularly by automobile manufacturers and international race teams, KW's in-house 7-post drive dynamics test facility is utilized to optimally tune KW coilover suspensions according to the design and target group. The 7-post drive dynamics test facility is essential for fine tuning along with actual on-road evaluation on public roads and race tracks. In objective laboratory conditions, which can be reproduced at any time, we work everyday to give our customers the internationally-esteemed KW driving experience.
  • Technical Component Report. The technical component report is always included in the package and outlines the guidelines for lowering the suspension of the respective vehicle. The technical component report ensures the vehicle remains usable when set within the guidelines provided in the installation instructions, allowing for an inspection and subsequent entry into the vehicle documents to be carried out without any problems. The technical component report also includes precise vehicle classification, requirements, and tips for safe fitting.These reports are required for road legal approval in many countries, check local laws.

KW is the Benchmark for coilovers. KW Variant 3 "inox-line" coilover rewards the sporty driver with its harmonious pre-configured setup. For each vehicle our engineers develop a specific damper setup and spring rate to increase the driving pleasure with an optimal balance of sportiness and practicality. As with all KW coilovers, the engineers at KW develop the vehicle-specific KW damper tuning and spring rates with comprehensive testing on the Nurburgring Nordschleife and in the KW 7-post chassis dynamics test center. You are not buying a mass produced, generic coilover kit, a KW coilover has been developed specifically for your particular vehicle. As a manufacturer, KW uses only its own resources, high quality components and the damper technology that has all developed in-house. With the KW Variant 3 "inox-line" coilovers, body roll will be reduced during compression giving you the benefit of a more genuine and direct sporty handling while driving.

Exactly what I was looking for
Color: White, Size: 26x26 Inch
I bought these to fill some euro pillow covers and they worked out really well. They come vacuum packed, so at first they look flat, but once you open them and give them a little time, they fluff up nicely. They are soft but still have enough structure to hold their shape on a bed or couch, which is exactly what I was looking for. Not overly firm, but not limp either. They give that full, styled look without feeling stiff. The size is true to 26x26 and fills the covers well without looking saggy. I like that they don’t feel hollow like some cheaper inserts can. Quality feels good for the price. They are not luxury pillows, but definitely a solid option for decorative use and they hold up well. Overall, really happy with them and would buy again for other rooms.

Smells amazingly like cherry, but expect a mess under the feeder.
Style: Wild Bird Food, Style: Wild Bird Food
This is a fantastic budget seed blend to keep your backyard feeders full during the busy seasons. I put a banana in the picture next to this massive 10-pound bag for scale, though I wouldn't recommend leaving the fruit out there unless you want to feed the local raccoons instead. The most surprising part of this bag is the smell—it has a very strong, sweet cherry scent right out of the bag that genuinely seems to bring in the local cardinals and blue jays faster than plain seed. THE GOOD: • The cherry flavoring actually works as an attractant, and the sheer volume of seed you get for the price makes this an excellent value for high-traffic yards. • It brings in a huge variety of ground-feeding birds, especially mourning doves and juncos. THE TRADE-OFF: • This is a "value" mix, which means it contains a very high percentage of filler seeds like milo and cracked corn. Finicky songbirds will actively kick the milo out of the hanging feeder to get to the black oil sunflower seeds, creating a massive pile of rejected seed on the ground. THE BOTTOM LINE: A great-smelling, budget-friendly birdseed that attracts a ton of wildlife, provided you don't mind the ground-feeders cleaning up the mess underneath.

Has attracted a mix of birds.
Style: Wild Bird Food
Great value for the price. Since putting this out, we’ve had so many different kinds of birds visiting our yard. The birds seem to love the mix, and it has definitely brought more activity to our feeders. I also compared prices before purchasing, and this was very comparable to similar products and bag sizes. Overall, it’s a quality bird seed at a fair price, and I would absolutely buy it again

Great for local birds
Style: Wild Bird Food
This bird seed has been a great find for attracting birds here in North Texas! Within just a couple of days of putting it out, we started seeing a noticeable increase in activity. It brings in a nice variety too—cardinals, finches, doves, and even the occasional blue jay. The mix seems fresh and well-balanced, with very little waste. I also appreciate that it doesn’t have a ton of filler seeds that birds usually ignore. Everything in the blend actually gets eaten, which makes it feel like a better value. It holds up well in our unpredictable Texas weather, and I haven’t had issues with mold or clumping. Overall, if you’re looking to attract a wide range of local birds and keep your feeder busy, this is definitely worth trying!

Great Bird Attraction & Solid Value for the Price
Style: Wild Bird Food
This bird seed has been a great addition to our yard. It attracts a wide variety of birds + they seem to really enjoy the cherry flavor.. it doesn’t sit untouched like some other mixes I’ve tried. The quality is solid, with a good mix that looks fresh and not overly dusty. It also seems easy for the birds to digest, as they keep coming back + there’s minimal waste left behind. I mean.. enjoying the bird without the poop - WIN! The 10-pound bag is a great size.. enough to last a while without constantly needing to restock. For the quantity you get, it’s definitely good value for the money. Overall, a reliable choice if you’re looking to attract more birds without overspending. If your debating.. BUY NOW
