The Eibach Sport-Plus kit for 2011–2012 Ford Mustang Shelby GT500 includes Sportline springs and sway bars matched for that specific model and years. It’s offered as a coordinated suspension package to replace both springs and anti-roll bars together, simplifying upgrades for Shelby GT500 owners. The overview keeps attention on the vehicle-application pairing and the included components rather than technical spring rates.
