The AST lowering spring set for BMW 4 built between March 2014 and July 2021 lowers ride height and reduces the car’s center of gravity while keeping much of the OEM ride comfort. These vehicle‑specific springs are cold‑coiled on Wafios machines and feature a progressive wind to balance lowered stance with handling. Sold as direct OEM replacements, they include a lifetime warranty against breakage and cover thousands of compatible applications.
