The AST lowering springs for BMW 4 (from November 2020) lower ride height and reduce the center of gravity while preserving much of the OEM ride 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 reliable long‑term use and broad model support.
