Product Details
The Swift Sport Lowering Springs for the 2007-2015 Infiniti Q40 lower the Q40 (formerly G37 sedan) for improved handling and a sportier appearance without sacrificing daily-driver comfort. These Q40 lowering springs provide an approximate 1.2" front and 0.8" rear drop, designed to complement the stock sport suspension. Built in Japan from Swift's proprietary H5S.TW material, these Q40 springs reduce body roll and improve turn-in response, making the most of the VQ37VHR's naturally aspirated power on twisty roads and highway on-ramps.
