The H&R Sport Spring kit for 1999-2004 Ford Mustang Cobra V8 (with IRS) lowers ride height to reduce fender‑well gap, lower center of gravity and reduce body roll for improved handling, while a progressive spring rate maintains ride comfort. Built from 54SiCr6 spring steel, shot‑peened and block‑set for resilience and low weight; H&R’s Sport Springs are a top German‑made suspension upgrade.
