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.

Great idea
Color: Blue, Size: 28" x 34"
This is a great product mainly because it holds down the pads and if anyone has tried to do the inside to outside training that was a huge plus to have it not blowing away constantly the only reason. For the 4 star and not 5 is the middle tends to have a lump of bunch up cause it does not have a section to cover but only way to make this better is to have the top be completely seperate but either way better then most I have tried

Great investment! It'll save your floors and help train your pup by giving him/her a specific area to pee/potty in the house!!
Color: Blue, Size: 17" x 23", Color: Blue, Size: 17" x 23"
Though my pup sometimes like to pee right at the edge of this puppy pad holder, when he does, he usually just hits the lip of holder. He's a beagle/dachshund mix, and will probably end up around 20lb - he's around 15-ishlb now - so not a tiny dog, but is still a small dog. And with him being "not" tiny/toy, and him being a male, he tends to not aim so well sometimes when he uses it. This made using the PP holder a learning curve for me.
I started out using the regular size pads in it
, which fit amazing well; however, with Morty's - ahem! - mishaps with aiming, I tried doubling-up on the training pads - would put two of the reg size pads on the holder - and that left just enough pad "hanging" outside of the holder to meet Morty's mishaps in aiming. I was even able to still fasten the holder through the pad, which is awesome!
However, using double to pads to cure Mort's lack of ability to aim for the center every time was costly, so I decided to shop around to see if I could find a solution to our aiming whoes. That's when I stumbled upon these pads at Walmart for just under $10 before tax, but they are available to purchase here at Amazon,
& it occurred to me that perhaps one XL pad would give Morty that extra allowance he needed, and it could be more affordable to me - it worked! .
These particular pads have been working out wonderfully because I continue to use just one pad and still get the overage protection - I'm pretty sure Morty intentionally pees on the edge sometimes - but since they're quite absorbent, it's very rare that he misses so much that he pees "through the pad." [The time he pees through the pad are the times he literally barely even hits the holder/pad at all because like I said, I'm pretty sure he aims for the edge on purpose most of the time.]
Since Morty is a beagle/dachshund mix, he is a scent hound, which means that I can never just "let him outside" - I always walk him outside with a leash - because scent hounds follow their noses [pretty sure his nose is more Beagle than Dachshund lol]. And with it being extremely hot out now, I allow him to pee indoors at least 50% of the time; I am absolutely thrilled that he has taken to his wee-wee pad like a pro.
All and all I'm very satisfied with this purchase because it has allowed us to have a clearly defined, and mostly contained space within out home for our pup Morty, to go potty in the house, and without ruining our hard floors. Moreover, since the holder itself is plastic, cleaning it up is a breeze! I just spray a bit of Clorox Clean-up on the holder, wipe it and voilà - odor-free home!
As an aside; the holder mentions being skid proof, and though I don't doubt the validity in that claim since the feet, which are on the four corners, do have rubber on the bottom, Morty is still a 7-month-old puppy, and sometimes, he can be a bit ornery and play with his pee-pad - which is always fastened inside the holder. And that subsequently allows him to move the holder from it's original spot because he "pulls" it since he's trying to "pull" the pee-pad off. Also, when my daughter and her friends play fetch with him, sometimes they'll throw his tow toward the same area that his holder sits. When that happens, he tends to run across the pad/pad holder and cause it to move. I'm attaching a video to illustrate what I mean. On this particular day Morty was playing by himself with an empty two liter bottle - he loves bottles! On this occasion, his pad/holder is not in it's normal spot - he's actually moved it into the kitchen. Toward the end you can here him baying out the door at someone/thing. I believe it may have been the neighbor lol :)
But since the times that Morty is able to move the holder are during times in which his doing it intentionally, I still wouldn't dock it for "not" being skid proof because it clearly is. I just wanted to point this out in case you furry family member is anything like mine, and is full of energy - I don't think there much of anything in my house Morty can move when he has high-energy like that. Also in the video, you can see how the XL pads fit onto the regular size holder, and the extra overage it provides - should you have a dog like Morty who needs a little extra overhang because of his aiming woes. I've also included photos of my pup, Morty. He'd climbed up on the chair for no reason really, but it's another example of his high-energy :)

Does what it says
Color: Dark Gray, Size: 22" x 22"
I was using just a puppy pee pad on the floor, but when my puppy started to become rambunctious....she'd quickly grab it and play with it...shred it and try to eat it. I also noticed that she tended to only want to use the edges of the pee pad majority of the time....so I typically ended up with it on the pee pad and then a puddle next to it. I had to do something. On Amazon I go like always and I found this. Didn't even know this existed. Works beautifully. I've had this for around 2 months now. Fits standard pee pads perfectly. It cleans easily. It doesn't hold in any odor. This does not completely keep my puppy from peeing on the floor. This is not the products fault, she aims towards the edges for whatever reason. If anything, it's helped keep more of it in. The raised edges do seem to encourage her to stay inside of it. We rarely have "accidents" now and no more shredding pee pads. See below.
*On another note- she has scratched at the pee pads, like she's digging in the dirt for gold as well as chewed on the plastic a fews times. I was worried I'd have to find another solution. She gets redirected with her chew toys and gets a treat every time she uses it correctly (no chewing or digging). At this time it doesn't seem like it will be an issue that I need to address. She hasn't done it since. So if your dog is determined this will NOT stop them. This product is not indestructible, please know this! It can be chewed on and if determined they can still get to the pee pad. I don't understand why some people rate it poorly when the product is doing what it's "intended" to do. You just have to know your situation and find the best solution you can live with. A dog is going to be a dog. Please address why they are doing what they're doing to begin with. I realized that my pup (*puppies will chew) wasn't getting enough mental stimulation, she's an Aussie. She had physical but not enough mental stimulation. Combine that with making sure we only encourage the wanted behavior and simply dismiss the unwanted behavior. I'm not saying I'm a pro, far from it... nor is everyone's situation the same....I'm just saying don't expect a product to do your job, expect what it says it's intended use is for. :)

NO GO!
Color: Dark Gray, Size: 22" x 22"
I was really hoping this would work, but it did not. The minute I put the tray down with puppy pad secured, my puppy managed to chew and dig at the edges ripping the pad away from the side of the tray and making a huge mess! I am not returning it bc this company makes you take it to UPS which is not convenient for me, so maybe I will donate it. If your puppy is massive chewer this may not be the thing for you.

Great idea.
Color: Dark Gray, Size: 22" x 22"
Great concept! Unfortunately, the plastic area underneath the pad area isn’t very thick and flexes. When my dog used it the first time the plastic flexing up and down under her feet frightened her a little bit. I placed a rubber mat between the pee pad and the flimsy plastic and that stopped the plastic from flexing but since it scared my dog from the first use she won’t go back on it.
