This coilover suspension upgrade is designed to achieve a perfect balance of street comfort and increased performance. This suspension system allows you to easily adjust your ride height while improving handling performance of your car.
Our patented scaled system design allows easier and more precise adjustment and ensures equal height on each corner. Each shock is equipped with 24 levels of dampening adjustment to fine-tune the valving efficiency.
The Part : KI19-IS coilover shocks are handcrafted and assembled to your specs at SCALE facilities.
This model front Macpherson configuration comes with adjustable camber plate front top mounts to set your desired camber specs and avoid excessive tire wear. We recommend using the gravitational bearing option to reduce the effort of the camber plate.
This rear divorced spring configuration uses a linear spring. Custom spring rate or length is not a problem.
Shock has no direct impact on wheel alignment, so if you need more adjustment than what your car offers from factory, you can check if a specialized company offers adjustable control arms.
Our mono-tube shock absorber are using high-quality CNC piston valves, synthetic oil and high-pressure nitrogen gas contained within one tube.
As this application uses a specifically shaped spring, only the regular version is available and the custom spring rate or Swift spring upgrade only applies to the linear spring of this application. The swift upgrade price is for 2 springs only.

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.
Hi Matthew, thank you for your detailed review! We're glad to hear you're enjoying the performance improvements. Sorry about the sticker mix-up and the lack of response—I will pass this feedback to our team to improve our communication and packaging. Additionally, we apologize for wording in the instructions. We have it converted from French to English as were Canada based. We appreciate your support and hope your Kia continues to handle great on those turns!
