The AST lowering springs for BMW 4 xDrive (from March 2021) lower the vehicle's center of gravity while maintaining much of the OEM ride comfort as a direct replacement. Cold‑coiled on Wafios machines with a progressive profile, they balance a lowered stance with improved handling. Vehicle‑specific fitment, premium materials and a lifetime warranty against breakage offer dependable long‑term reliability and coverage across many supported models.
