Overview

The Swift Sport lowering springs are a set of four performance springs designed for the 2014-2019 Infiniti Q50 AWD. These springs lower the vehicle by 1.5 inches in the front and 1.4 inches in the rear to improve handling and aesthetics while maintaining ride comfort.

Constructed from proprietary H5S.TW material, these springs feature a unique design with fewer coils to reduce un-sprung mass and increase usable stroke.
Show original supplier description
The Swift Sport lowering springs are a high-performance solution for the 2014-2019 Infiniti Q50 AWD, engineered to enhance handling while preserving showroom-quality ride comfort. By reducing body roll and squat, these springs provide better suspension balance for both street and circuit use. These springs are manufactured using a proprietary H5S.TW material, which offers a faster transient response to road conditions compared to standard alternatives. The design utilizes fewer coils, which helps to eliminate the risk of coil bind and effectively increases the usable suspension stroke. This approach avoids the common issues of harshness and premature shock wear often associated with lowering a vehicle beyond its functional limits. With a drop of 1.5 inches in the front and 1.4 inches in the rear, these springs provide a refined stance tailored to the specific characteristics of the Infiniti Q50 AWD chassis. Each spring is tested to ensure that it balances aesthetic improvement with functional performance, allowing drivers to achieve a lower center of gravity while maintaining the vehicle's intended driving dynamics.
