Superior Comfort & Handling: Unlike typical lowering springs, Swift Sport Springs are engineered using a proprietary steel alloy (H5S.TW) and unique winding methods. This combination ensures superior comfort and handling, addressing the usual issues of harsh rides experienced by enthusiasts.

Track-Ready Spec-R Springs: Designed for track duty, the Swift Spec-R Springs push boundaries by being built at the upper limits of OEM shock valves. These springs undergo rigorous track testing and tuning, maintaining showroom-quality ride while optimizing performance.

Enhanced Performance Characteristics: Utilizing the same engineering and material as the Sport Springs, the Spec-R Springs feature a higher spring rate and modified ride height, maximizing optimal suspension geometry for track enthusiasts seeking top-tier performance.

Innovative Coil Design: Swift Springs employ a coil design with fewer coils, reducing un-sprung mass and eliminating coil binding, thereby increasing usable stroke. This design ensures superior responsiveness and a smoother ride even on rough roads.

Quicker Transient Response: The proprietary H5S.TW material offers a quicker transient response, delivering a smoother ride on harsh surfaces compared to traditional springs.

Enhanced Suspension Tuning: With Swift Sport Springs, both street and circuit users can expect an increase in suspension tuning performance and comfort, elevating the driving experience in various conditions.

Elevate your driving experience with Swift Sport Springs – where engineering innovation meets superior comfort and enhanced performance on both the street and the track.

Very comfy ride and perfect ride height

The perfect drop

In my opinion this is the perfect amount of drop and ride quality for the person that's looking to get rid of the wheel gap and still retain an almost OEM like ride. From what I can tell under regular driving conditions it's just as compliant as factory but when you start to drive it a little harder it starts to stiffen up. Very good set of springs, 100% recommend.

So install is amazing. Quality is amazing. Car is lower and way way better thru the twisties. Definitely would recommend these over other springs. Also these are the highest rated springs over the stocks.
