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