Honda Civic Si Coilover Suspension Kit – BLOX Racing Plus Series Fully Adjustable (2017–2027). A performance-focused, fully adjustable coilover system tailored for the Civic Si, built for drivers who want precise control over stance and handling with daily reliability.

Engineered specifically for the Civic Si, the Plus Series offers a wide ride-height range and adjustable damping so you can fine-tune response for city streets, canyon runs, or weekend events. Refined valving helps reduce body roll and improve stability, supporting confident turn-in, better mid-corner balance, and composed braking. Designed to install using factory-style mounting points, it provides a straightforward upgrade path to a sharper, more predictable chassis.
