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