Product Details
The Swift Sport Lowering Springs for the 2006-2013 Lexus IS250 RWD (GSE20L) lower the IS250 for an improved stance and sportier handling characteristics while preserving Lexus's signature ride comfort. These IS250 lowering springs deliver an approximate 0.8" front and 0.6" rear drop, tuned to work within the stock damper's valving range for a controlled, refined ride. Made in Japan from Swift's proprietary H5S.TW material, these IS250 springs reduce body roll and sharpen steering response, making your daily commute and weekend canyon drives noticeably more engaging.
