The ST XA coilover kit for BMW 330i xDrive (4WD) delivers wide height adjustment and 16-click rebound damping to tailor driving behavior without sacrificing comfort. It uses galvanized steel struts, a wear-resistant polyamide composite spring perch with stainless insert to prevent corrosion, and a dust protection system; each damper is dyno-tested and comes with setup guidance.
