ST XA adjustable coilovers for the 2018-2024 Ford Mustang (S550, non-electronic dampers) combine a wide range of ride-height adjustment with 16-click adjustable rebound damping, letting you tune driving dynamics from comfortable to sporty by hand. Each kit uses zinc-galvanized steel struts, a friction-optimized polyamide composite spring perch with a stainless-steel insert for corrosion-free height adjustment, and an elastomer bump stop with integrated dust protection. Built by hand by KW in Fichtenberg, Germany, every damper is shock-dyno tested and ships preset to ST's recommended damper settings.
