The D2 Racing D-HN-22 Coilover Kit is a performance suspension upgrade for the 2006-2011 Honda Civic SI model. This kit is designed to provide superior handling and adjustability for enthusiasts looking to take their vehicle to the next level.
The D-HN-22 Coilover Kit features high-quality race-spec monotube damper units, which provide consistent and stable damping performance throughout the entire stroke. The damper bodies are made of solid 6061 aluminum, offering both durability and lightweight properties. The ram tubes are also made of the same aluminum alloy, ensuring a robust and long-lasting construction.
One of the most significant features of this coilover kit is the adjustability it offers. The ride height can be adjusted through the silver anodized top mounts, providing a range of up to 100mm (approximately 4 inches) of height adjustment. The damper force can also be manually adjusted by changing the position of the 16-stage click adjusters, allowing drivers to tune the damping characteristics to their preference and driving conditions.
This kit also includes Inverted Strut Mounts that replace the OEM rubber mounts, reducing NVH (Noise, Vibration, Harshness) and providing a more direct feel from the steering wheel to the road. Part of the kit's superior handling capabilities comes from the included camber plates, which offer up to 2.5 degrees of adjustability, and adjustable toe plates (sold separately) help ensure optimal tire contact with the road surface.
Additionally, the kit utilizes high-quality, lightweight, and durableSweden-made Bilstein springs with different rates for both front and rear applications, tailored to the Honda Civic SI chassis to provide optimal handling balance and ride quality. The springs are adjustable to allow fine-tuning of the vehicle's ride height.
Installation is relatively straightforward, with most users reporting the process taking around 3-4 hours for a first-time install. All necessary hardware is included in the kit, along with an installation manual and detailed illustrations.
