Application: 2012-15 Civic Non Si / 2012-13 Civic Si (Does not fit 2014-15 Si)
Spring Rates: F-8K / R-9K
The K1- Super Low Series coilovers are designed for those wanting to push the static limit of their car. Reduced strut body, spring length, and piston travel have all been used to lower the car as much as possible while still maintaining a functional suspension setup. The goal was to allow for the most drop without needing costly modifications. The rear strut features an eccentric (Off center) inverted strut with custom spring mounting. You no longer have to adjust spring and strut separately. Installing the spring on the strut allows us to gain move leverage as the spring has moved farther from the pivot point and increasing the travel while reducing the workload. This design allow greater drop and control over the suspension. The eccentric design (Off center top and bottom) of the strut allow us to push the coilover just a little more while not compromising the spring size or travel. We do this by putting the top and bottom mounting points off center to allow proper fitment and ultimate drop. Adjustment of the dampening is done through the bottom. Included with 9th gen coilovers are adjustable sway bar end links.
The K1-Super Low and K1-Street coilovers share many similarities and don't sacrifice quality at any point. The K1-Super Low ride height is meant to start where the K1-Streets end, meaning the K1-Super Low at the highest will be close to or lower than the K1-Street Coilovers. Stock ride height will not be possible with the Super Low coilovers.
K1-Street 2 - 3.5 inches
K1-Super Lower 3.5 - 5 Inches
Starting with the strut, we invested a lot of time to ensure that they are both durable and reliable. We 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. We finish 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. We do not just use a stiffer spring at the suspension to compensate for a poor quality strut; instead we made sure to start from scratch and build a complete coilover that will differentiate itself from the rest.
Next we pair the struts with a high-tensile strength steel spring that is designed to last without sagging or premature wear. 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.
Note: With K1-Super Low there may be fitment problems with larger exhausts and change in wheels/tires/offset. Rubbing may occur with drastically reduced suspension travel. If you're looking for a comfortable ride we recommend sticking with the K1-Street Coilovers.
