The KW Variant 1 "Inox-line" coilover kit is our entry point into our street performance lineup. Thanks to the high-quality "Inox-line" stainless steel coilover struts, corrosion resistant springs, bumps stops and dampers that are optimally tuned by our engineers the result is a balanced and sporty feel specific to each vehicle application designed for long lasting driving pleasure. The KW Variant 1 "inox-line" coilover allows you to experience an optimized balance of sportiness and comfort while driving. Even with a maximum vehicle load, the dampers always maintain a sporty characteristic. With KW Variant 1 coilovers you can achieve maximum lowering within an approved lowering range that ensures a proper functioning suspension and 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 1 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.
  • 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 1 "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 N?rburgring 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 1 "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 Magnesium source!
Flavor Name: Unflavored, Size: 90 Count (Pack of 1), Flavor Name: Unflavored, Size: 90 Count (Pack of 1)
I have tried many forms of Magnesium in the past, it’s an essential mineral for the body (regulates over 300 functions). It helps with sleep, blood pressure, cognitive function, mood, muscle cramps, and ATP production (the powerhouse of the cell). Science talk aside, I have tried Magnesium Glycinate and Citrate, and they can do a number on the gut, moving things along too quickly! Magnesium L-threonate has become very popular, but I am very picky about my supplements and the companies that make them. Jarrow Formulas is top notch! I have started looking for supplements that are more “bio-available” as they are better absorbed and used by the body. This supplement does all of the above, without upsetting my gut and making it overactive. I ran out of this supplement a few months ago, money was really tight, and it really affected my sleep, which is priceless! It also has L-threonate, which promotes sleep and positive mood. I am happy to have this back in repertoire, combined with vitamin D once a week (50,000IU), and Calcium Hydroxyapatite (see my other reviews, also super bioavailable). If you are looking for a Magnesium source that helps you sleep and regulate body functions without the side effects on your gut, this is a standout choice that works great!

My Monthly Magnesium Supplement
Flavor Name: Unflavored, Size: 90 Count (Pack of 1)
I have been ordering the Jarrow Formulas Magnesium L-Threonate, MagMind on repeat every month because it has become an essential part of my routine. I take it consistently to support brain health, memory, and overall cognitive function, and I’ve noticed it helps me feel more focused and mentally sharp. The capsules are easy to take, and the supplement seems to absorb well, which is important for magnesium effectiveness. I appreciate that it’s high-quality and reliable, which is why I keep coming back every month without hesitation.

Jarrow is a trusty brand, Magmind is superior for cognition, spatial relations and SLEEP QUALITY - UPDATED REVIEW
Flavor Name: Unflavored, Size: 90 Count (Pack of 1)
I have been using Jarrow Formula supplements for a number of years, especially the Vitamin B12 - methylcobalamin and Vitamin K2 - MK7 supplements. I have been impressed with their continuing development of new *effective* products at a great price point. My husband and I have been taking approximately a gram a day of supplement Magnesium (cheaper products) for almost 5 years now. In that time we have cured his former type 2 diabetes (after almost a 2 decade battle with medicated fasting BGs in the 500s at one point!) and we have almost completely reversed his hypertension of many years as well has have turned his end stage Severe Congestive Heart Failure around so he's relatively free of symptoms. I credit not only the magnesium, but also high doses of Vitamin D (ALWAYS taken with magnesium and fish oil!!), a whole foods source multi, the Sinatra Protocols for supplements as found in the back of and a number of minerals especially trace minerals as found in . I was looking into research on magnesium and the brain when I ran into the MIT study published in 2010 showing magnesium L-threonate is the only form of magnesium to cross the blood-brain barrier and showed observable improvements in cognitive measures. Interesting. So we bought a bottle at our local neighborhood nutrition shop after a discussion with the owner, a couple I have come to trust during our many battles with the medical establishment. Jarrow Formulas of magnesium L-threonate as Magmind is a very cost-effective source. To further economize we are still taking our regular magnesium supplement 3 times a day (750 mg) then taking this form of magnesium as part of our bed time routine (replacing the 4th magnesium of the day). I am genuinely impressed. Our sleep has improved yet another notch, which is saying something since the 5 years of magnesium supplementation meant we already had really good sleep quality. What I have noticed is that after multiple head trauma injuries (including a serious concussion earlier this year) my previously very high level of spatial relations was slipping. Now with Jarrow I feel I'm getting that edge back. I am very impressed. I will update again with further results after we've been taking this formula longer. 2015 UPDATE - in the years since we first tried MagMind I've referred hundreds of people to try this quality supplement with great results. We've since learned to couple magnesium with taurine for even greater results. Taurine is VERY well documented to improve the fluidity of electrolytes within the cells including within the brain. NOVEMBER 2016 UPDATE: Well, here we are 4 years later. We still personally use and recommend MagMind. What we discovered though, since he was put on Armour Thyroid by our primary care he no longer seems to be "leaking" magnesium hence we've cut magnesium supplementation waaayy back. Plus we soak in epsom salts far more. Magnesium is still vital however we're no longer "taking a gram a day."

Works like magnesium, not certain on brain benefits. I like the brand.
Flavor Name: Unflavored, Size: 90 Count (Pack of 1)
I take magnesium near-daily and have for some time due to my diet. Mostly it's glycinate, though sometimes I'll take some citrate. This is my first experiment with l-threonate. Before I get into this, I am not taking this as directed. I take 2 capsules during the day and usually take a different type of magnesium toward evening. I have about 40 capsules left, so I've taken a bit more than half the bottle so far. Supposedly magnesium l-threonate may give you brain benefits over other types of magnesium. If it does, I'm not sure. It seems to have the same, general magnesium benefits for relaxation, sleep, muscles and nerves, but I don't notice any clear indication that my brain is working better: I'm thinking clearer, faster or am sharper mentally. This could be happening to a small degree, but other changes I've made could lead to this as well, so the waters are muddy there. I'm going to cycle back to magnesium glycinate after I'm done with this bottle, or maybe open up my magnesium optimizer (also by Jarrow -- magnesium malate, b6, potassium and taurine), then come back to this again. See if there's any noticeable difference in my mental capabilities or focus. If I seem to see an association, I'll update this. I like the brand. I've used their Magnesium Optimizer before and was pleased with that (bought another bottle), their fulvic acid / shilajit -- that seemed to work. I'm a fan. This magnesium is more expensive than other types, but at present I'm not sure that extra cost is worth it over a different type of magnesium.
