ST Suspensions XTA Coilovers - BMW M3 (F80) / M4 (F82) 2015-2020

The ST XTA coilover kit for the F80 BMW M3 and F82 M4 gives you height-adjustable suspension with 16-click adjustable rebound damping, a linear race-spring system, and aluminum unibal camber-adjustable top mounts at the front axle. Each kit is hand-built by KW in Fichtenberg, Germany on galvanized zinc-coated steel struts and dyno-tested to factory-preset damper settings before it ships. The friction-optimized polyamide composite spring perch with a stainless-steel insert resists corrosion while keeping ride-height adjustment smooth over the long term.
