The ST X coilover kit for Mini Cooper S (F55) blends everyday road comfort with sporty handling through a wide range of ride-height adjustability and tuned dampers. Composite spring perches with stainless-steel inserts prevent corrosion and make height changes easy; galvanized zinc-coated struts, a dust protection system and vehicle-specific tuning deliver a balanced, user-friendly suspension upgrade.
