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