Swift made Sport Springs keep the quality ride you get from the showroom, and adds improved handling and lower ride height for driving enthusiasts and style minded drivers who demand only the best. They utilize a spring design with fewer coils which not only allows them to decrease un-sprung mass but to also completely eliminate the chance of coil bind, while increasing the amount of usable stroke. their proprietary material (H5S.TW) has a much quicker transient response, reacting to any road conditions which, in turn, cause a much smoother ride where other springs will skip on the harsh road surface, their spring will react to the road surface as needed.With the Swift Sport Springs, both street and circuit users can experience an increase in all aspects of suspension tuning from performance to comfort.
