The AST lowering springs for BMW 4 (from July 2021) reduce ride height and lower the center of gravity while maintaining much of the OEM ride comfort as a direct replacement. Cold‑coiled on Wafios machines with a progressive profile, they deliver a controlled lowered stance and enhanced handling. Vehicle‑specific fitment, premium materials and a lifetime warranty against breakage provide dependable long‑term reliability across a wide range of supported models.
