The ST XTA coilover kit is a height- and rebound-adjustable suspension system for the 2018-2024 S550 Ford Mustang, fitting EcoBoost, GT, Mach 1, Bullitt, Shelby GT350/GT350R and GT500. It pairs linear race springs with 16-click adjustable rebound damping and aluminum unibal camber-adjustable top mounts that sharpen steering response and let you dial in front camber for aggressive wheel and tire fitment. Galvanized zinc-coated steel struts with a friction-optimized polyamide composite spring perch and stainless-steel insert resist corrosion for long-lasting ride height adjustability. Built by hand by KW in Fichtenberg, Germany and dyno-tested before shipping, each kit ships with a damper setup manual.
