Tailored Performance Enhancement: Developed specifically for Civic Sport/Si models, Swift Spec-R springs are crafted to enhance the vehicle's unique characteristics, offering both a luxurious ride and a sporty feel while boosting overall performance.

Performance with Comfort: Designed for driving enthusiasts and style-conscious drivers, these springs deliver improved handling and a lowered ride height without compromising on ride comfort, ensuring a balanced driving experience.

Track-Ready Design: Engineered for track enthusiasts participating in HPDE events or SCCA competitions, the Spec-R Sport Springs are crafted to push your vehicle's performance boundaries while maintaining ride comfort.

Advanced Engineering for Comfort: Unlike conventional lowering springs that compromise ride quality, Swift Sport Springs utilize a proprietary steel alloy (H5S.TW) and unique winding methods to provide superior comfort and handling.

Optimized for Track Duty: Track-tested and tuned at the upper limits of OEM shock valves, the Spec-R Springs offer optimum performance while preserving the quality showroom ride, featuring a higher spring rate and modified ride height for optimal suspension geometry.

Reduced Unsprung Mass: Utilizing a spring design with fewer coils, these springs reduce unsprung mass, eliminating coil binding and increasing usable stroke, enhancing both handling and responsiveness.

Quicker Response: The proprietary H5S.TW material ensures a quicker transient response, delivering a smoother ride even on rough roads, elevating suspension tuning performance and comfort for street and circuit use.

Elevate your Civic Sport/Si's performance and ride quality with Swift Spec-R Springs where superior engineering meets driving pleasure, providing an unmatched balance between sporty handling and luxurious comfort.
