AST lowering springs for 2005–2009 BMW Z4 reduce ride height roughly 30mm front and rear while maintaining much of the OEM ride comfort. They act as direct OEM replacements to lower the center of gravity and improve stance and handling without excessive stiffness. Cold‑coiled on Wafios machines with a progressive rate profile, these vehicle‑specific springs balance looks and driving stability and include a lifetime warranty against breakage.
