The H&R Sport Spring kit for 2011–2014 Hyundai Sonata (YF) lowers ride height to reduce the fender‑well gap and sharpen handling characteristics. Its progressive spring rate reduces body roll and lowers the center of gravity for improved stability and driving feel, with a modest aerodynamic benefit that can aid fuel economy. Built from 54SiCr6 spring steel, shot‑peened and lightweight to balance sporty response with everyday comfort.
