About this product
For chassis code E82 (Coupe)
Swift made lowering Springs keeps 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.
EVERY CAR HAVE THEIR USABLE STROKES.
Most enthusiasts have had experiences with the typical harsh and uncomfortable ride from lowering springs. Performance is often overlooked by manufactures simply because it is easier to lower a vehicle for aesthetics. The end result is usually a bumpy ride that causes a decrease in traction, or excessive worn shocks caused by lowering the vehicle beyond the usable stroke.
Swift utilize spring design with fewer coils which not only allows to decrease un-sprung mass, but to also completely eliminate the chance of coil bind, while increasing the amount of usable stroke. Swift designed 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, our spring will react to the road surface as needed.
SPORT SPRINGS.
Swift did not develop their Sport Springs line by simply dropping the ride height. Unlike other manufacturers whose sole focus was style, Swift approached the creation of these lowering springs with 3 goals.
- MAINTAIN OR IMPROVE A SMOOTH, COMFORTABLE RIDE.
- INCREASE HANDLING BY REDUCING BODY ROLL AND SQUAT IN SEARCH OF OVERALL SUSPENSION BALANCE.
- LOWER THE VEHICLE WITHIN TOLERANCE OF EACH VEHICLE’S USABLE STROKE.
With the Swift Sport Springs, we expect both street and circuit users to experience an increase in all aspects of suspension tuning from performance to comfort.
SPORT SPEC-R SPRINGS.
Swift Spec-R Springs are designed at the upper limits of the OEM shock valving. Track Tested and Tuned for optimum performance yet keeps 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.
Swift Spec-R Sport Springs were engineered with 3 characteristics in mind.
- MODIFIED RIDE HEIGHT COMPARED TO SPORT SPRINGS TO MAXIMIZE OPTIMAL SUSPENSION GEOMETRY.
- FURTHER INCREASING THE SPRING RATE TO ENHANCE OVERALL PERFORMANCE. THE INCREASE IN SPRING RATE IS BASED ON THE UPPER LIMITS OF THE VEHICLES FACTORY SHOCK VALVING.
