The AST lowering springs for BMW 4 (from July 2021) lower the vehicle's center of gravity while keeping much of the OEM ride comfort as a direct replacement. Cold‑coiled on Wafios machines and engineered with a progressive spring profile, they balance a lowered stance with improved handling. Vehicle‑specific fitment, premium materials and a lifetime warranty against breakage ensure reliable, long‑term use and broad compatibility across many models.
