K2 Pro-Circuit 2-Way Coilovers are designed for cars looking to set track records and leave with 1st place finishes. All K2 Pro-Circuit 2 Way Coilovers feature 12 way dampening and rebound adjustment. They come with stronger internals to handle all the abuse you can throw at them. Stiffer spring rates and more aggressive valving is set on K2's to keep the car stable in the corners. To make sure they will handle lap after lap K-Tuned paired up with Swift Springs to offer their own custom spring for all K2's. They all feature pillow ball upper mounts including older vehicles with double wishbone suspension.

K-Tuned's goal was to design a suspension setup that is reliable race coilovers built with the best components. All setups feature adjustable ride height and 12 way dampening and rebound to adapt the ride to your preference. K2 Pro-Circuit 2-Way have remote reservoir and rebound adjustment to further adjust and setup the car to your driving style.

Starting with the strut, K-Tuned invested a lot of time to ensure that they are both durable and reliable. They start with a durable heat-treated steel piston and needle valve to ensure proper travel and linear compression ratio. The strut body is designed to handle the heat and the life cycle it will be put through. Each strut is filled with proprietary oil that is designed to maintain its viscosity even under increased heat or abuse. The oil will keep its unique properties over the years to maintain that same ride quality. This is crucial to the quality and longevity of the strut. Poor quality suspension setups use cheaper oil that can become frothy, lose its strength and degrade overtime. These inferior suspension systems will lose their fluid movement and/or become too soft. K-Tuned finishes the strut piston with longstanding, high-heat rated double seals that are designed to take abuse without breaking a sweat, literally. No leaking struts here. The strut is the most important part of any suspension system. It determines the ride quality and the overall feel. K-Tuned does not just use a stiffer spring at the suspension to compensate for a poor quality strut; instead they made sure to start from scratch and build a complete coilover that will differentiate itself from the rest.

Next they pair the struts with a high-tensile strength Swift Spring that is designed to last without sagging or premature wear. Swift Springs have proven themselves to last longest into a race without fatiguing. Springs are tested to ensure there is no coil bind and full range of motion. The high quality strut and dampening allows us to use the proper spring rates needed for each setup that will complement the adjustable dampening rates. Each spring is mounted on adjustable aluminum perches that can be used to adjust preload and travel. Incorporated washer and spacers are in place to keep the system free moving especially on McPherson style struts.

The coilover system is finished with a combination of powder coating, electroplating, and anodizing to give it a great look and protect it. McPherson style struts feature adjustable upper camber plates and pillow ball mounts when applicable

Promising Skincare Product with Clean Ingredients
I have always loved this brand and have purchased many of their skincare products in the past, so I was excited to try their Volufiline after seeing how popular it has become on TikTok. A lot of people online claim it helps plump the skin and reduce the appearance of fine lines and wrinkles without needing injections, which definitely caught my attention. For the price, I think it is a pretty reasonable product if it actually delivers results. From what I understand, this is not a product that gives instant results and it can take at least three months or longer of consistent use before you really notice a difference. Because of that, I cannot honestly say yet whether it works or not, but I plan to continue using it and will update my review over time if I start seeing visible changes. I also purchased a separate roller ball attachment for the bottle because it makes application much easier and more precise. Without the roller attachment, you would mostly be applying the product with your fingers, which can apparently cause your fingers themselves to become plumper from repeated contact. As always, one of the things I appreciate most about this brand is the transparency and focus on clean ingredients. Their products always feel thoughtfully formulated, and I like knowing exactly what I am putting on my skin. Overall, I am hopeful about this product and excited to see the long-term results.

Good skincare. Just okay for wrinkles and fine lines
I’m not sure it’s filling in wrinkles but it’s not hurting either. I kind of think once your a certain age there isn’t a lot of change that happens with surface level products. It’s kind of more about slowing the aging process versus reversing it. Reversing may only happen in a surgeons office or by treatment from a medical esthetician. That being said I do think this product is offering me support by slowing down the aging process and reducing new lines and wrinkles. My skin definitely has a dewy appearance after using this product. The product is lightweight and goes on like a light oil. It is a tad greasy when it’s first applied but it does absorb well. I try to put this on when I have time to let it absorb a little but I have also been in a rush and had to go straight into makeup application after using. I didn’t have any issues with the quick transition. As with most of the Ordinary line the prices are economical for skincare. I give this 4 stars only because I didn’t really see a change/improvement in my current fine lines and wrinkles. I do think overall it’s offering some benefits. The bottle is small but the amount needed per application is small. You have to shake the product out of a little restricter cap which is kind of annoying. I think a tiny dropper would make for better dispensing and less waste. As with all my facial serums and skincare products, I always rub any remaining product on the tops of my hands.

Let’s Be Honest… I Bought This Hoping for Magic
Let’s be honest-anytime a product says “plumping” or “volume,” my expectations immediately split into two categories: absolutely nothing happens, or I convince myself something happened because I spent money on it. This one actually surprised me. The texture is lightweight but nourishing, and because it’s anhydrous, it feels a little richer without being greasy or heavy. I started using a small amount consistently in areas where my skin looked a little tired or less full, and over time my skin definitely started looking smoother, healthier, and more refreshed overall. One thing I really appreciate is that it doesn’t just sit on top of the skin making you shiny for five minutes and then disappear into disappointment. It absorbs well, layers nicely with the rest of my routine, and leaves my skin feeling soft instead of sticky. The biggest thing I noticed is that my skin just looks more “awake” and healthy lately-like I’ve been drinking enough water, sleeping properly, and making responsible life choices…which may or may not be true. I’ve tried a lot of skincare products that sounded impressive and did very little. This one actually earned a permanent spot in the routine.

Good product
I've used a few different volufiline’s and I like this one best. You get a tingling sensation that you don't get from other brands. Most of them are around the same price but this brand seems to have a bit of a larger bottle. I recommend purchasing this product. My smile lines are reducing significantly. I stopped putting it on my under eyes because I read somewhere it can make them worse. You also have to continue using it to keep the changes.

This makes my face feel amazing
I love how this makes my face feel! It’s still early to tell how effective it’ll be, but I saw friends yesterday that I hadn’t seen in almost a month and they commented how well rested and useful I looked! It was pretty flattering
