METRIC COILOVER SPRING
MORE STROKE, INCREASED TRACTION AND HANDLING, LESS UN-SPRUNG WEIGHT. THE ONLY THING YOU WILL BE LOSING IS LAP TIME.
Swift's innovative designs have made us a staple in the performance tuning world. Our products are the result of over 90 years of experience in industrial spring manufacturing. Our engineers have spent countless hours developing and re-developing our springs, in order to create a product that is light, durable, and compliant, while still maintaining linear spring rates.
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.
These springs are designated by (Diameter)-(Free Height)-(Rate)
Z70 = Diameter 70mm
178 = 178mm Free Height
240 = Rate in N/mm
