Kia K4 2025+ Innovative Series Coilover

overall I’m very happy with the product and the experience. The suspension itself feels very high quality. Everything arrived as expected, and I ordered mine with the upgraded Swift springs and stainless hardware. From the packaging to the components, the setup felt well-built and solid. The installation went pretty well overall. The main downside is that the instructions could use some refinement. They were a bit vague in certain areas, so I had to use my car’s factory service manual to help guide me through removing the OEM suspension and installing the new parts correctly. For someone with less mechanical experience, clearer instructions would definitely help. The other issue I ran into was that my front coilovers were mislabeled. The left front was labeled right front, and the right front was labeled left front. That caused some confusion and added extra time during the install. Once I figured it out, everything went together, but that was definitely something that could have been avoided. That said, the customer service was excellent. Before ordering, I had a lot of questions, and even after the coilovers arrived, I had several technical questions during the install process. The sales team and tech support were very responsive, often getting back to me within an hour. That made a big difference and gave me more confidence throughout the process. thanks Josh!! Overall, I’m impressed with the quality of the suspension and the support from Scale. My only real feedback would be to improve the installation instructions and double-check labeling before shipping. Other than that, it was a very positive experience, and I’m excited to continue dialing in the setup.

The coilover installation was relatively easy for someone with just a surface level understanding of suspension components. However, when the fronts got here the stickers letting you know which one was for the left and which one for the right were swapped. I also lost my stickers instantly (which is of my own fault,) but when I emailed asking for possible replacements I got no reply. All of the negative out of the way, on a good note. I took a gamble on rather these would fit or not, a 1700 dollar gamble. Id say it was worth every cent. Yes, the ride handles a little bumpier than OEM, but thats just coils. These let me stick to the ground at speeds up to 80 on some of the turns I take when before 70 would be the cap. The instructions could be refined, typos and all. However, they do a very good job explaining what's what. All in all, I enjoyed my purchase for the most part. I'm sure you will too.
