The AST lowering springs for BMW 4 (from July 2020) reduce overall ride height and lower the center of gravity while keeping much of OEM ride comfort as a direct replacement. Cold‑coiled on Wafios machines and engineered with a progressive profile, they provide a controlled lowered stance and improved handling. Vehicle‑specific fitment, premium materials and a lifetime warranty against breakage ensure dependable long‑term performance.
