Description

Enhance the performance and stance of your 2022+ Lexus IS 500 with Swift Spec-R Springs. Designed as performance-oriented lowering springs, they sharpen cornering response, reduce body roll, and provide a sportier, more aggressive look—all while retaining Lexus comfort for daily use. Part # 4T921R, these springs are tuned specifically for the Lexus IS 500 platform. They feature a front spring rate of 6.5 kgf/mm and a rear spring rate of 10.0 kgf/mm, with a corresponding drop of -1.0 inch in the front and -0.6 inch in the rear. This tuning aims to strike the perfect balance between street comfort and race-inspired suspension performance.
