K-Tuned K1 Street Coilovers for the 2014-2015 Civic Si are designed to give you the best ride quality without sacrificing any comfort or reliability. 

• This coilover set features adjustable ride height and 12 way dampening to adapt the ride to your preference.
  
• We start with a durable heat-treated steel piston and needle valve to ensure proper travel and linear compression ratio. 
  
• 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.
  
• 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.
