Sport Lowering Springs

The Swift Sport Lowering Springs (part number 4N910) are engineered to provide an improved driving experience for the Infiniti Q50 AWD, model years 2014 and newer. Swift developed these springs with three primary goals: maintaining or improving ride comfort, increasing handling performance by reducing body roll and squat, and lowering the vehicle's ride height within its usable suspension stroke. These springs utilize Swift's proprietary H5S.TW material and a unique manufacturing method. The springs feature a design with fewer coils, which helps to decrease un-sprung mass and eliminate the possibility of coil bind, while simultaneously increasing the usable suspension stroke. The H5S.TW material provides a quick transient response, allowing the springs to react smoothly to road conditions, preventing the harshness and skipping often associated with lowering springs. The intended outcome is an increase in all aspects of suspension tuning for both street and track use. Specifically, these springs lower the vehicle by approximately 1.5 inches in the front and 1.4 inches in the rear. The spring rates are set at 8.0 kg for the front and 4.2 kg for the rear, which are designed and tested to work effectively with the factory shocks and dampers. Swift tailors each Sport Springs application to the individual vehicle's characteristics, aiming to preserve the luxury feel of a luxury car or the sports car feel of a sports car.
