These coilovers feature advanced 3-way adjustability, allowing users to fine-tune rebound, high-speed compression, and low-speed compression independently. The shock absorbers are equipped with external canisters for precise adjustments, offering 12 rebound positions, 12 high-speed compression settings, and 14 low-speed compression options. Constructed with durable materials and engineered for track use, these coilovers deliver superior handling, stability, and responsiveness. Their adjustable features enable optimal tuning for various driving conditions, making them ideal for enthusiasts seeking competitive performance.

Designed for 1995-2000 Honda Civic Si models with the EJ9 chassis, these coilovers are a direct bolt-on upgrade for stock suspension systems. They are intended for track, racing, or spirited driving, providing enhanced cornering, reduced body roll, and improved overall control. Installation involves replacing the factory struts with these adjustable units, allowing for precise ride height and damping adjustments. The kit includes the coilover assemblies with external canisters for compression adjustments, ensuring comprehensive tuning capabilities. Suitable for street or track use, these coilovers are ideal for drivers aiming to maximize their Civic’s performance and handling characteristics.
