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.

Best product I've tried so far but still temporary. YMMV.
Size: 1 Count (Pack of 1)
This product really does work. It is the best I've used. I purchased in September 2024 and am writing this review in May of 2026, roughly one year and 8 months later. I noticed product failure a little after a year after application and it has been degrading slowly since. Currently the product is visible like a layer of clear paint flaking off and you can physically scratch some off. Here are the pros and cons. Pros: Clarity, relative ease of use, value Cons: Taping and sanding, doesn't last for as long as you own your car as claimed Best used as a temporary fix. Bottom line, would I use it again? Yes. What am I doing today? Replacing the headlights completely. Why? I plan on keeping my car for longer than a year.

Review After Using on 3 Different Cars over 3 years
Size: 1 Count (Pack of 1)
Cerakote Headlight Restoration Kit : After Using on 3 Different Cars over 3 years This is my second time purchasing the Cerakote Headlight Restoration Kit, and I’ve now used it across three different vehicles. At this point, I feel comfortable saying this product genuinely works when used correctly. Before trying this kit, I considered replacing my headlights entirely. The cheapest replacement set I found was around $150 just for the parts. Installation would have required removing the grille, bumper, and other components, which adds time and complexity. For an older vehicle, that didn’t make financial sense. Instead, I chose to restore the original headlights. Cost and Value My first package cost me $17, and I restored two cars with that single kit ( about 9$ per pair). That alone made it worth it. For under $20: I restored two separate vehicles Avoided buying new headlight assemblies Avoided removing the bumper and grille Compared to a $150+ replacement plus labor, the savings are significant. Durability 1 year+ under direct Cali sunlight (currently on year 2 and still good) First Car – Learning the Process The first time I used the kit, my results were decent but not perfect. That was mainly because I didn’t fully understand how sanding and polishing actually work. ( this reoxidized fastest under 8 months, but it was mostly my fault) I didn’t initially realize: The headlight needs to stay wet during sanding Oxidation must be completely removed before applying clear coat Even pressure matters/ 50% overlap coverage when appling ceramic Once I understood that sanding is the most important step, everything improved. Second Car (beater) Major Improvement The second vehicle was heavily oxidized and yellowed. I used the remaining material from that same $17 kit and restored it completely. The clarity difference was dramatic. It looked close to factory condition, and night visibility noticeably improved. That was when I realized the product itself is solid; the key is proper technique. Third Car ; Recent purchase By the third car, the process felt straightforward. I followed the instructions carefully, kept the surface wet while sanding, and applied the clear coat evenly in one smooth pass. The final result was clear, glossy, and uniform. No haze, no streaking. Durability On my first vehicle, the restoration lasted close to a year perfectly( I sold that car this year and it still had clear headlights), and that car was parked outside in direct sun most days. For a DIY kit at this price point, that level of durability is impressive. Final Thoughts I seriously considered spending $150 on replacement headlights( this was cheapest ) and dealing with removing body panels. Instead, I spent $17 and restored two cars. Now having used it on three vehicles, I can say this kit is effective, cost-efficient, and worth the time if you follow the process properly. It does require effort and patience, but the results justify it. I would purchase it again.

works as advertised!
Size: 1 Count (Pack of 1)
I purchased this kit to renew the headlights on my 2016 Nissan Frontier pick-up. The headlights had become slightly oxidized and dull -- not that bad but it was bothering me and for the price of the kit I figured it was worth the effort to attempt to renew them. All I can say is -- WOW, what a difference. The end result looked like new -- clean, brilliant and bright. Read the directions (2 or 3 times) and follow them EXACTLY. Total time for me from opening the kit to being done was about 2 hours and I was taking my time. This kit is different in that the final step applies a UV resistant coating which really makes the glass super transparent. Great investment in the time and money. I can't stop admiring my new (old) headlights!

Incredible Results! The "Z-Line" is Back!
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
I’ve tried a few "wipe-on" fixes in the past, but the CERAKOTE® Ceramic Headlight Restoration Kit is in a completely different league. If you are tired of hazy, yellowed lenses and weak nighttime visibility, look no further. 📖 Instructions & Ease of Use The first thing that stood out was the clarity of the instructions. The kit breaks everything down into a simple, step-by-step process. Even if you aren't a "car person," the directions are foolproof. They don't just tell you what to do; they explain why each step matters, which gave me the confidence to get the job done right the first time. ✨ Restoration Effectiveness As you can see in my Before and After photos, the transformation is night and day. My headlights went from a dull, oxidized yellow to a factory-fresh, crystal-clear finish. It didn't just "clean" them—it completely rejuvenated the plastic. 🔦 The Real Test: Light Output & Beam Pattern The most impressive part isn't just how the car looks, but how it performs at night. I’ve included a photo of my car parked against a wall in the dark to show the comparison: Passenger Side (Restored): You can see a sharp, distinct cutoff line and the perfect "Z-line" pattern. The light is focused exactly where it needs to be on the road. Driver Side (Not Restored yet): The light is completely distorted. There is no cutoff, just a messy blob of light that scatters everywhere, likely blinding oncoming traffic while providing less actual visibility for me. Final Verdict This kit doesn't just make your car look better; it’s a genuine safety upgrade. Seeing that crisp Z-line back on the wall proves that the clarity is internal as well as external. Highly recommended!

My first experience using one of these, it worked VERY well!
Size: 01- 24pcs (Classic Green)
Our tire picked up a large bolt that we could hear clicking when we were driving, and our low pressure warning light lit on our dash. Yep---tire was 7 psi below recommended (32 down to 25), I could not see the leak site and we were far from home so I drove some more then checked again. Just one more psi down over those 20 miles so all the way home (100 miles more) we drove. By that time I was able to find the leaking spot and see the bolt head had ground off or broken off. It was just a very slow leak, a few psi more per day, but I knew it would only get worse. I decided to order this kit after reading reviews & don't believe the haters. It worked so well for me it is worthy of my time to write of my experience. The tools to me all seem robust & top notch, especially for the price. There are multiple straps inside the nice case to secure them in place. YES---you have to use your own pliers but come on---don't ding the product when that is spelled out clearly in the description! So---I had the huge benefit of allowing a full day in my own garage to do this. I pulled the wheel since others had said it much easier that way. I then used my pliers to pull the remaining bolt out of the tire and immediately heard the air rush out. "That's a pretty big hole!" I thought. I reamed the hole easily, lubed the plug installation tool, centered one plug strip in the tool and pushed it in all the way except about 1" left outside the tire. I aired up the tire after about 5 minutes of what I thought would be "cure time" but don't know if that's necessary. After my initial inflation to full pressure the tire actually did leak down a bit over a few hours. A few cycles of this and it has stayed sealed completely ever since....not even down a pound! I assume this was the time the vulcanizing compound (already applied to the plugs) took to seal to the tire....maybe if I had driven on it right away (heat generated and varying forces) it would not have leaked out. My initial fear of "huge hole" and assuming I might need to plug twice or use 2 plugs the fear was unfounded. I will update this post if something goes awry. For now I am one happy customer as well as a happy camper. I'd strongly recommend this kit based on my experience, plus I have the remaining patches & tools if needed again. I hope this helps you with your decision/choice.
