Description
The Dežru Spec-S Coilover System is engineered for the 2016–2021 Honda Civic, offering a performance-oriented suspension upgrade designed to balance precise chassis control with everyday driving comfort. Developed for the 10th-generation Civic platform, the Spec-S combines digressive monotube dampers, linear-rate HyperCoil springs, and adjustable damping to help deliver a more controlled and responsive driving experience.
Designed for drivers who use their Civic as a daily vehicle but also enjoy spirited street driving, canyon roads, and occasional autocross or high-performance driving events (HPDE), the Spec-S emphasizes predictable handling rather than excessive stiffness. Its digressive piston valving is designed to provide supportive damping during initial steering inputs, braking, and rapid transitions while maintaining compliance over uneven pavement and ordinary road imperfections.
The system features fixed-length damper bodies and an adjustable ride-height range of approximately 25–50 mm below factory height, allowing owners to tailor the vehicle's stance to their preferences. When properly configured, the setup aims to improve body-motion control while maintaining practical suspension travel and predictable handling.
With its specified 350 lb/in front and 400 lb/in rear spring rates, the Spec-S provides a balanced foundation for a street-focused performance suspension. The final handling characteristics will depend on the Civic's specific variant, damper settings, alignment, tires, and ride height.
Key Features
-
Digressive Monotube Dampers: Designed to deliver controlled body movement and responsive damping during braking, cornering, and directional changes.
-
Fixed-Length Damper Bodies: Engineered to support consistent suspension operation within the system's intended ride-height range.
-
Adjustable Damping: Allows suspension response to be fine-tuned for daily driving, spirited street use, and occasional performance events.
-
Vehicle-Specific Spring Rates: Features 350 lb/in front and 400 lb/in rear springs, as specified for this application, to support chassis control and predictable handling.
-
Linear HyperCoil Springs: Designed to provide consistent spring response throughout suspension compression.
-
Adjustable Ride Height: Offers approximately 25–50 mm of lowering for a sportier stance and a lower center of gravity.
-
OEM-Style Upper Mounts: Intended to retain a refined street-driving character while helping minimize unnecessary noise, vibration, and harshness (NVH).
-
Hand-Built, Dyno-Matched Dampers: Prepared in matched pairs to promote consistent damping characteristics from side to side.
Performance Character
The Dežru Spec-S is designed to make the 10th-generation Honda Civic feel more controlled and responsive during everyday driving and more composed when pushed through corners. Its digressive damping profile emphasizes support during initial suspension movement, helping manage body motion during braking, steering inputs, and rapid changes in direction.
The specified spring rates aim to provide a balance between front-end support and rear chassis response. The slightly higher rear spring rate may influence the car's rotation characteristics, but the overall balance will depend on the suspension geometry, damper tuning, alignment, tires, and vehicle configuration.
On everyday roads, the Spec-S is designed to retain useful compliance over imperfect surfaces while providing a more controlled feel. For spirited street driving and occasional autocross or HPDE use, its adjustable damping offers additional flexibility to tailor suspension response to the driver's preferences and conditions.
Ride Height and Suspension Setup
The Spec-S offers approximately 25–50 mm of adjustable lowering compared with factory ride height. This range allows owners to choose a moderate drop for everyday usability or a lower stance for a more aggressive appearance.
For the best balance of comfort and performance, ride height should be selected with adequate suspension travel, ground clearance, and tire clearance in mind. A professional installation and four-wheel alignment are recommended after installation or significant ride-height adjustments.
Who Is It For?
The Dežru Spec-S Coilover System is suited to Honda Civic owners who want:
-
Improved chassis control during braking and cornering.
-
A more responsive steering and handling experience.
-
Adjustable damping for different road conditions and driving styles.
-
A sportier lowered stance without an excessively stiff setup.
-
A balance of daily-driving comfort and spirited street performance.
-
A suspension system suitable for occasional autocross and HPDE events.
