The AST lowering spring set for BMW 4 built between March 2014 and July 2021 lowers ride height and reduces the vehicle’s center of gravity while keeping much of the OEM ride quality. Cold‑coiled on high‑grade Wafios equipment with a progressive wind, these vehicle‑specific springs balance a lowered stance and improved handling. Offered as direct OEM replacements, they are backed by a lifetime warranty against breakage and fit thousands of applications.
