Product Details
The Swift Spec-R Lowering Springs for the 2016-2020 Lexus GS F (URL10) lower the GS F's center of gravity to better harness the 5.0L V8's power through corners and high-speed transitions. These URL10 GS F lowering springs provide an approximate 1.3" front and 1.0" rear drop with spring rates of 8 Kg/mm front and 14 Kg/mm rear, tuned for the GS F's Adaptive Variable Suspension and Torque Vectoring Differential. Built in Japan from Swift's proprietary H5S.TW spring steel, these GS F springs deliver a more connected driving experience with reduced body roll and improved steering feedback.
