2014-2021 Infiniti Q50 (RWD) Sport Springs by Swift

Swift made Sport 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. Swift did not develop the 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.

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.

As you can imagine, keeping or improving the comfort level while increasing performance is not an easy task, especially since these two aspects contrast with each other. Where most of the competition simply gave in to the easier method, Swift Springs decided to tackle this issue by creating our own material (H5S.TW), and unique manufacturing method that works very well for this material. Working in unison, the material and manufacturing method provides a superior level for both comfort and handling.

Swift utilizes 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, causes a much smoother ride. Where other springs will skip on the harsh road surface, a Swift spring will react to the road surface as needed.

Features

• Maintains or improves a smooth, comfortable ride
