Benefits of 4 Inch Springs
Many enthusiasts will swap springs from brand to brand with the only noticeable difference being a stiffer or softer ride. But what if a spring could offer a noticeable increase in traction, smoother weight transfer, better ride quality, lower tire temperatures, and a more predictable feel? The engineers at Swift have taken that "what if" and turned it into reality.
All Swift Springs are manufactured using (H5S.TW.) which is far superior to silicone chrome steel and allows us to wind our springs with less coils, resulting in reduced un-sprung weight and increased stroke. Since the metric system is used widely in the sport compact and road race market, we have introduced the metric line of coilover springs to reduce confusion and to better cater to our customer's needs.
