1-Year Manufacturer Warranty

Swift Springs offers a limited 1-year warranty on their metric coilover springs against defects in materials and workmanship. This warranty applies to springs that are properly installed and used under normal conditions. Swift Springs will repair or replace defective springs at their discretion.

Product Details

Swift Sport Lowering Springs, part of the Swift Springs lineup, for the 2007-2015 Infiniti Q40 are designed at the upper limits of OEM shock valving. These springs lower the center of gravity, reduce body roll, and sharpen handling response while remaining comfortable enough for daily driving. Both Sport and Spec-R options are excellent for street use, offering a ride that is slightly stiffer than factory suspension for a more controlled, sporty feel.

Developed for track duty and proven in HPDE and SCCA competition, Swift Sport Springs were engineered with three critical traits in mind: optimized ride height to maximize suspension geometry, increased spring rates tuned to usable shock stroke, and retention of streetable comfort. Using proprietary H5S.TW material and a unique manufacturing process, Swift achieves a rare combination of comfort and performance where most competitors compromise. Fewer coils reduce unsprung mass and eliminate coil bind, while quicker transient response improves traction and road feedback. Swift also focuses on bump rubber design and vehicle-specific tuning—ensuring luxury cars keep a luxury ride and sports cars retain their sharp, sporty character.

    Swift lowering springs

    For those that want a mild drop and still feel oem like. I paired these with koni shocks and it feels a bit stiffer but nothing too harsh. Great ride for daily driving.

    Swift Sport Lowering Springs for 2008-2013 Infiniti G37x Sedan AWD
    Rated 5 out of 5 stars
    Perfect drop

    Installation was straightforward and the springs gave me the perfect drop. Rides like stock on smooth roads but potholes are definitely more aggressive. Definitely the way to go if you want to get rid of the wheel gap on the awd G.
