Product Details
The Swift Sport Lowering Springs for the 2008-2011 Lexus IS F (USE20L) lower the IS F for an improved stance and sharper handling that better matches the 5.0L V8's performance capabilities. These IS F lowering springs provide an approximate 1.0" front and 0.6" rear drop, designed to work with the IS F's sport-tuned adaptive suspension. Built in Japan from Swift's proprietary H5S.TW material, these IS F springs reduce body roll and improve high-speed stability while preserving the refined ride quality that separates the IS F from harsher track-oriented competitors.
